Men & Mice at VMworld 2018, Las Vegas Part 1: DATA CENTER AND CLOUD

Posted by Greg Fazekas on 7/30/18 6:30 AM

men_mice_dns_vmworld2018

We’re returning to VMworld in Las Vegas, August 26-30 (Booth #2124, come say hi!) — and excited to not only see how our industry is evolving to virtualization and automation, but to also contribute our two cents to the dialog (Or 9.1 cents, as it were).

Since the newly released Men & Mice Suite v9.1 offers highly scalable and efficient APIs that act as an abstraction layer to manage an organization’s whole DNS, DHCP and IP address infrastructure, across multiple vendors and cloud platforms, we’re focusing on two main tracks from the VMWorld agenda: Data Center and Cloud and Networking and Security, the first of which we’ll discuss in this post (the latter will appear in the next post).

DATA CENTER AND CLOUD

VMworld’s focus on integrated IT strategy plays nicely with the Men & Mice Suite v9.1 release (and our larger objectives as well).

Men & Mice has been providing compatibility with VMware’s vRealize Orchestrator and vRealize Automation for years now. As the industry turns toward virtualization and cloud technology to build its next-generation, hyper-converged infrastructure in hybrid cloud environments, running cloud-native applications to cut costs and increase efficiency, so to have we adapted our Men & Mice Suite of DNS, DHCP and IPAM solutions to help organizations manage networks effectively and at scale.

The Men & Mice Suite v9.1 supports Unix/Linux, Windows, and Cisco IOS and stretches into the cloud with functionality across Azure DNS, Amazon Route 53, Dyn, NS1 and Akamai Fast DNS, as well as IPAM in AWS, Azure and OpenStack.  It can be dropped on top of an organization’s existing infrastructure to manage, sync and automate network changes, authorizations and provide comprehensive insight into large-scale networks through one unified dashboard.

The Men & Mice Suite v9.1 supports thousands of concurrent users and API connections, with millions of managed IPs and DNS records, for automation and provisioning.

Virtualized Infrastructure and Applicationsmen & mice_secure_visible_dns

We favor virtualization over physical appliances and platform-specific, custom hardware allocation. Turns out, our customers do too.  We want our customers to be able to make the right choices for their network infrastructure (DDI) needs. Then, we offer our environment- and platform-agnostic Men & Mice Suite to help them manage it.

Virtualized infrastructure is both cost and performance efficient. Men & Mice Suite gives organizations the flexibility and adaptability they need as every area of business operations goes digital, providing the managaibility and visibility needed for high-availability networks to be, well, highly available.

Our new Men & Mice Suite v9.1, an overlay network management solution, offers many advantages for virtualizing and automating, as well as increasing visibility and ease-of-management of an enterprise organization’s network infrastructure, including its new web-based management application, which takes the “daunt” out of day-to-day operations and reporting.

Another way we’re making virtualization easier is through the Men & Mice virtual appliances, the DNS software for which we’ve upgraded to BIND 9.11, supporting various new features as well as DNSTAP. For example, details on DNS queries received and DNS replies sent by the Men & Mice virtual appliances can now be logged for further processing by enabling and utilizing the powerful DNSTAP feature with minimal performance impact on the appliances. They can also function as NTP (Network Time Protocol) servers and be served by the same network infrastructure as DNS and DHCP.

men_mice_hybrid network managementPrivate, Hybrid, and Public Clouds

Every cloud vendor is different. Different platforms and configurations offer different advantages (and drawbacks) for customers. They also offer very different, and often incompatible APIs. Men & Mice Suite v9.1 services complex enterprise hybrid and multi-cloud networks by providing single-pane-of-glass visibility and cross-platform functionality for DNS, DHCP and IPAM (DDI) operations, whose networks use either multiple cloud (cloud native) vendors or a combination of on-prem and cloud (hybrid).

The ability to bulk migrate DNS zones and DHCP scopes, ability to implement role-based authorizations, as well as providing 3 management interfaces (Windows-based management console, web-based management application and REST, SOAP and JSON-RPC APIs), the Men & Mice Suite v9.1 overlay software solution eliminates many of the complexities of today's large-scale networks while mitigating DNS failures such as configuration errors and DDoS attacks.

Further, Men & Mice Suite's xDNS Redundancy provides a level of abstraction that builds automation, provides centralized views, eliminates human error and removes conflicting DNS service provider platform complexities (e.g. incompatible APIs).

The Men & Mice Suite v9.1 also allows organizations to add Active Directory zones to xDNS groups. This, tied with the read-only members of xDNS groups, makes it easy for organizations to bring their internal, on-premises DNS into their virtual private clouds, and vice versa.

Cloud operations monitoring, a topic to which we’re looking greatly forward discussing at VMworld, is transparent and easy in the Men & Mice Suite v9.1. Not only have we integrated true cloud DNS into the Men & Mice Suite, but we also paid attention to the cloud-unique challenges it brings with it.

Can’t make it? No worries!

Network virtualization with visibility and automation of DNS, DHCP and IPAM

Posted by Greg Fazekas on 7/16/18 8:45 AM

The Men & Mice Suite version 9.1, released last week, introduced several new features and improved functionality for hybrid and multi-cloud networks. One of the additions we developed in our mission to change the way the world sees networks is a cross-platform, easy-to-use web-based management application.

Seamless integration

We intend the web-based management application for the Men & Mice Suite to be the go-to interface for the most common tasks. In the future, it will also serve as the central platform for our innovations across DNS, DHCP and IPAM (DDI). We're highly focused on developing an increasing number of partnerships to make integration across services and vendors even more seamless.

Day-to-day DDI operations made simple


With three major sections — DNS, Networks, and Reporting — the Men & Mice web-based management application is organized around operational efficiency.

Where the existing Windows-based management console of the Men & Mice Suite gives you the full range of configuration and management options for your networks, the web-based management application focuses on day-to-day tasks, such as finding and working with DNS zones or records, IP address ranges, DHCP scopes and IP addresses. You may want to use the full Men & Mice Suite application for the yearly inspection or the large restructuring of your networks, but can quickly get things done from anywhere, on any device, with the web application.

Quick Commands: lightning-fast, best-in-class user experience

men_and_mice_quick_command

Another way the web-based management application helps to efficiently manage networks is through its Quick Commands feature.

If you ever used the Spotlight functionality in MacOS or the universal search bar in other platforms or services, you know how a deceptively simple function can save incredible amounts of time. The Quick Command feature interacts with a single click or key combination (ctrl+space) and uses auto-complete to arrive at the needed information or function in just a few keystrokes. 

We’ll continue to focus on and add functionality to Quick Commands in future releases. As it gets smarter, so to will your network management get easier.

Visit the Men & Mice Suite web-based management console guide for more information on its capabilities and full functionality.

Virtualization and automation 

In addition to our virtual DNS/DHCP appliances and Virtual DNS Caching appliances, in a larger context of network management, the v9.1 release of the Men & Mice Suite continues to forge its path towards greater network virtualization and automation. The Men & Mice Suite restores and significantly improves the unified network visibility usually forfeited in the process of virtualization, intuitively pulling data from critical network components and consolidating it in an easy-to-use UI with extensive centralized control and functionality.

The Men & Mice Suite offers unrivalled integration with Microsoft Active Directory Sites and Subnets, combined with real-time synchronization across diverse server environments and distributed virtual and physical locations.

The comprehensive built-in tracking and logging tools ensure the systematic keeping of records. It's important to know who made what change, when, where, and why. Transparency takes the sting out of the fast and dynamic change procedures that are the hallmarks of virtualized environments.

Access management is granular and fully integrated with Active Directory. Role-based access provides strong, centralized control and delegation. Different IT teams experience painless cooperation and efficiency, respecting the often hazy task boundaries created by the transformation from physical machines to virtual instances.

The Men & Mice roadshow continues!

men&mice_vmworld_Booth #2124

What we do at Men & Mice is help companies with large, complex network infrastructure automate and virtualize their networks. We also believe in the value of other forms of networking-- meeting customers and future customers in person.

We’ll be exhibiting at VMworld in Las Vegas August 26-30, to showcase the Men & Mice Suite at booth# 2124.  We'll report in on our social media and on this blog — hope to see you either there!

Men & Mice Suite 9.1: cloud-ready network management for DNS, DHCP and IPAM

Posted by Men & Mice on 7/11/18 7:47 AM

Changing the way the world sees LI

Our commitment to efficient network management has a new number! The Men & Mice Suite 9.1 is a feature release with a host of cloud-ready enhancements plus the usual suspects (bug fixes and improvements).  

Network Management just got easier

Transparency, responsiveness, and ease-of-use are all core principles of Men & Mice for keeping networks healthy and safe from DDoS attacks and other DNS network failures.

The 9.1 release continues our mission to simplify network management without sacrificing features. Included in Men & Mice Suite v9.1:

  • A new web-based Men & Mice Suite management application
  • Optimized and enhanced cloud support
  • Improved xDNS Redundancy read-only zones for hybrid and multi-cloud networks
  • DNS software on appliances upgraded to BIND 9.11 with DNSTAP support
  • NTP functionality for virtual appliances
  • Various improvements and bug fixes

5 Things You’ll Love About Men & Mice Suite v9.1

Men & Mice Suite v9.1 focuses on features and refinements gleaned from customer feedback and engagement as well as refinements of previously introduced functionality. Here's what you will find in the new release: 

Web-based management application

The new web-based management application serves as an alternative to the Men & Mice Suite Windows-based management console. It’s designed to make performing day-to-day tasks, management functions and generating reports related to DNS and DHCP operations easier. The application features three sections: DNS, Networks and Reporting.

  • The DNS section makes all your DNS zones accessible from a single place.
  • The Networks section gives you instant access and overview of your networks.
  • Reporting lets you quickly find and run existing reports.

men_and_mice_quick_command-1

Its Quick Command functionality cuts down time on common tasks such as finding and working with DNS zones or records, IP address ranges, DHCP scopes and IP addresses.

Read-only zones in xDNS Redundancy groups

xDNS Redundancy, which can be used to synchronize DNS zones hosted with multiple cloud providers, now includes support for Active Directory-hosted zones. Zones in a redundancy group can be assigned to read-only mode, so that changes made to a DNS zone outside of the Men & Mice Suite will not be replicated to all other zone instances.

Optimized and enhanced Cloud support


Version 9.1 streamlines the migration and management of a large number of DNS zones with Azure DNS and Amazon Route 53 by utilizing cloud-native features to monitor changes to DNS made outside of the Men & Mice Suite, greatly improving synchronization of DNS data from the cloud providers.

Men & Mice virtual appliances upgraded to BIND 9.11 with 

DNSTAP support

DNS software on Men & Mice virtual appliances has been upgraded to BIND 9.11, which supports various new features as well as DNSTAP. Details on DNS queries received and DNS replies sent by the Men & Mice virtual appliances can now be logged for further processing by enabling and utilizing the powerful DNSTAP feature with minimal performance impact on the appliances.

NTP functionality for virtual appliances

The virtual appliances can also now function as NTP (Network Time Protocol) servers and be served by the same network infrastructure as DNS and DHCP.  Currently this functionality is manual and can be implemented per request with our support team. 

Nearly 30 years of DNS experience in one solution

The Men & Mice Suite v9.1 represents our commitment to enabling customers to adapt their infrastructure to be more software-enabled, cloud-ready and redundant, with increased visibility, control, security and automation.” --Magnús Björnsson, CEO of Men & Mice.

Complex enterprise network infrastructure can — and should — have the same elegant simplicity and responsiveness as IT professionals expect from customer-grade solutions. In the new release, Men & Mice has combined its nearly 30 years of expertise in developing DNS, DHCP and IPAM solutions with modern UX best practices to deliver a compelling, enjoyable management interface on top of a best-in-class, robust software-based DDI product.

In the first half of 2018, Men & Mice Training taught courses in five countries with students flying in from across time zones and from other continents. Participants came from three different ccTLDs, from national governments, and from both major enterprise corporations and smaller institutions.

We are proud of our reputation for delivering exceptional training courses, positive student feedback, and humbled by the effort that people make to attend. However, we're committed to making attending easier.

New DNS & BIND fall 2018 courses added

ddi_menandmiceFive new public courses have been added to our schedule this fall, from September through November 2018.

We've also begun soliciting student feedback on where we should hold our next courses. Based on initial feedback, classes have already been scheduled for two locations where we've previously never taught: Denver, Colorado, USA, and Geneva, Switzerland.

Our most popular public course is DNS & BIND Week (DNSB-W).

DNS & BIND Week is ideal for anyone just starting in the DNS world, but most commonly attended by those knowledgeable about DNS, and by experienced BIND administrators. Those with previous skills report that the start of the course, which assumes nothing, fills in gaps in their knowledge and corrects misconceptions, and the course moves on to unknown topics and new material. All Men & Men courses are hands-on, full of laboratory exercises. 

If you want to get trained ASAP, this is your chance.

Men and Mice @ Cisco Live: Intuitive IT through intuitive DNS

Posted by Men & Mice on 6/5/18 8:00 AM

Visibility in DNS management is more important than ever. As networks become increasingly hybrid and migrate to cloud environments, managing multiple vendor systems and consoles adds new complexities to enterprise DNS management.

Men & Mice minimizes these complexities, reducing network vulnerability by unifying distributed DNS networks in one management console, additionally filtering activity through audit trails for full visibility and reporting.

We're excited to exhibit at Cisco Live (#CLUS) again this year to showcase how intuitive IT benefits from intuitive DNS. 

We're looking forward to showcasing what's changed since we visited Cisco Live last year:

  • We released version 8.3 of the Men & Mice Suite with unprecedented stability, performance and scalability.
  • We introduced xDNS for multi-vendor DNS management in the cloud.
  • We doubled the size of our service team to better cater to our customers. 
  • We added Live Demo capabilities to menandmice.com and streamlined our customer on-boarding process.

Visit us at Cisco Live! We'll be at booth #1113.

The Future of DNS Management. The DNS Management of the Future.

Posted by Greg Fazekas on 5/25/18 9:50 AM

 

Unifying_decentralized_DNS

Streamlining network management (bringing together on-premise DNS, DHCP, and IPAM with multi-vendor cloud DNS and IPAM, compatibly) is more important than ever. Cloud-based systems and the rapid expansion of digitally connected IoT are driving infrastructure growth. It’s especially important for companies to have full visibility, authority and control across public, private, and hybrid networks.

The foundational technologies of DNS operations have stayed largely the same. DNS management, however, has changed and adapted - and keeps changing and adapting--  to meet the new challenges of business services and growth.

Centralizing the decentralization of DNS

As enterprise IT moves to the cloud, it creates the necessity to have effective DNS and IPAM in the cloud as well. Importantly, it’s also necessary to have cohesive communication and oversight between both on and offsite environments to maintain uptime, smooth network functionality and prevent vulnerabilities.

But making the switch to hybrid and migrating to the cloud can have its challenges, especially for those who already made significant investments in on-prem hardware and software, have numerous established DNS zones or who have large networks that they would need to bulk migrate. Further, navigating legal compliances across multiple geographic zones and ensuring data security at every connection point adds to the hurdles that companies face in maintaining, scaling, and updating their networks.

Men & Mice knows a thing or two about these changing infrastructure needs and has been focused on creating solutions that simplify complex environments for nearly 30 years. Our software not only helps companies effectively manage existing DNS and IPAM needs, but adapts to meet future needs as networks scale. Our overlay network management solution, the Men & Mice Suite, provides customers with unprecedented stability, performance and scalability.

Future of DNS and IPAM in the Cloud: A modular overlay solution

Flexibility and scalability require a multi-platform solution where the same automation can drive DNS deployment no matter if it’s with AWS, Azure, NS1, Dyn, Akamai or something else. It also needs to effectively managing complex networks by eliminating visibility gaps between traditionally different deployments in public cloud and on-premise private configurations.

Our xDNS Redundancy streamlines DNS management across multiple service provider platforms, helping to mitigate DDoS attacks and other forms of DNS failure by providing centralized management of critical DNS services.

Men & Mice Suite offers consolidated views in a unified console, secure monitoring and integrated management of all network spaces across platforms and on-premises, in the cloud, or in hybrid or multi-cloud environments. Additionally, authorized administrators are allowed to make changes directly through the Men & Mice Suite, with its robust access control, ensuring they can only change entries that belong to them.

Men & Mice has been at the forefront of network management for almost as long as there were networks to manage. We’ve been creating DNS, DHCP, and IPAM solutions for decades for on-premise networks and have evolved our software solutions to cater to the growing needs of network administrators tasked with managing cloud-based DNS and IPAM.

See you at Cisco Live!

menandmice_dns_CLUS_ linkedin

We love the theme of this year’s Cisco Live: IT that informs, connects, predicts and enables.It embodies the principles of the Men & Mice Suite. We'll be in Orlando, Florida from 10-14 June, to showcase the next generation of DNS and IPAM solutions for those overseeing the staggering number of IPs that comprise today’s DNS infrastructures. Visit us at booth 1113 to learn more.

Everything’s changed in DNS. Nothing’s different in DNS.

Posted by Greg Fazekas on 5/10/18 7:56 AM

globe_menmicelogo

The history of DNS (Domain Name System) starts with the earliest of early networked systems: ARPANET. DNS has often been characterized as the “phone book” for the internet — that analogy was, of course, invented  in an era where phonebooks were a thing.

It may be more fitting to liken it to a phone company switchboard. Even in the earliest days of ARPANET, however, the required communication was to send an email to Stanford Research Institute at Stanford University, where the hosts.txt file was maintained, to get a new Hostname into the list. Then, all Internet hosts updated the hosts.txt file twice a week via FTP file transfer. Twice a week... by FTP!

Interesting fact: whatever platform you’re using, chances are you can find a hostsfile somewhere on your computer. This is a remnant of the early ARPANET days. Back then, a simple static text file controlled the entirety of the network.

The Making of a Network (a.k.a. “everything has changed”)

As the networks grew, the need to wait became cumbersome, if not unbearable. Business was increasingly conducted outside of bank hours, and computers were moving data faster for us. So, why not use computing to handle IP assignments as well?

In 1983, the standard for DNS was accepted by the ARPANET community. By 1984, at UC Berkeley, we saw the advent of "Open Source" Berkeley Unix Distribution (BSD) and ported TCP/IP to Unix, making Unix a networked OS (under a DARPA grant) resulting in the first version of the Berkeley Internet Name Domain (BIND). To this day BIND serves as the de facto DNS software of the internet.

Thereafter, the Internet Engineering Task Force (IETF) was founded, and with it came new formal processes that have shaped the backend of the internet as we know it today.

Fast Forward To Now (a.k.a. “nothing’s different”)

You may be thinking: that’s interesting and all, but what does that have to do with my DNS network?

Well:  DNS hasn’t changed much in the last 4 decades. Of course, the explosive growth of the internet has changed the ways we map, scale and secure our networks. But the fundamental operating principles of DNS haven’t changed since its inception-- it’s still the switchboard of the internet. Instead of humans making a request through email, however, systems can call on DNS services, any time of day, to assign a multitude of IP addresses at a time.

The introduction of IPv6 (which has yet to be fully realized), and the dawn of cloud computing and IoT (Internet of Things) brought  significantly increased device requests and IP traffic.However, all that has not changed what DNS does; rather only how it does it.

We’ve Seen It Change and Stay the Same

DNS has changed very little; but the way we utilize it changed immensely. We've seen it: since the 1990’s, Men & Mice has serviced enterprise companies with DNS, DHCP and IPAM solutions.

We proactively evolve our overlay network management solutions to meet the needs of enterprise customers, and now high growth IoT companies as well. (Note: the two are not mutually exclusive.)

We are working with perhaps the most fundamental building (scaling) block of the internet. Our expertise is focused on the importance of adaptation. Network infrastructures have become hybrid, or have moved to the cloud completely. Multitudes of DNS services and environments have come to market introducing greater choices, but also complexities for network managers.

Men & Mice and the future of DNS

menandmice_unified_console_

Men & Mice has evolved its DNS, DHCP and IPAM solutions to cater to these changing environments. We adapted to become more flexible, so that the networks of our clients can migrate across network vendors easier. We created a  unified network management console to manage, in one place, all of the diverse platforms that make up a company’s network.

We’ve introduced new services such as xDNS in 2017 to help companies manage all external DNS. Likewise, we added deeper functionality with Microsoft Azure and Azure DNS for Microsoft customers with large domain portfolios.

We’ve streamlined our sales and customer journey processes, to reflect the same ease of use customers experience in our software solutions. Get a Live Demo directly from our website, for example.

We continue to offer some of the most sought-after training courses for companies and individuals who wish to learn or sharpen their understanding of DNS, enabling them to significantly increase expertise levels across their teams.

Meet our team

Join us in Berlin on May 15th, for a special event with the Embassy of Iceland in Germany. We will discuss the “State of Network Management” and the new challenges of DNS, DHCP and IPAM.

Or, meet us at Managed Service Hosting Summit, Cisco Live, Microsoft Inspire,VMWorld and Microsoft Ignite in the coming months.

Interesting fact: Bob Metcalfe, who invented the standard of the ethernet, predicted in 1995 that the internet would collapse in a year. He  also envisioned an end to wireless technologies, and that computers would stay wired.To his credit, he did — as per his promise — eat his words, literally, after none of those things happened.

Thinking of doing DNS better?

Posted by Men & Mice on 3/20/18 10:27 AM

I train, therefore I am

Or that’s what Descartes may have said if he’d been thinking his thoughts in 2018.

Mind you, this blog is not about thinking and it’s not about physical training either, like running or wife carrying or stuff like that. It’s more about training as in training for the mind. Learning useful things. Like how to configure BIND, debug DNS, figure out TSIGs or what DNSSEC can do for your network. Basically, the kind of training that helps you build a leaner, stronger, fitter network, and create the system resilience needed to deliver those constantly surging numbers of packets to their right destination, faster and more securely.

Version 8.3 – Faster, Leaner, Fitter DHCP

Posted by Johanna E. Van Schalkwyk on 1/11/18 11:16 AM

Doing DHCP

The beauty of DHCP is the speed at which it functions. Basically, DHCP (Dynamic Host Configuration Protocol) does what administrators can do manually, but DHCP just does it automatically, more efficiently, and in a fraction of the time.

Size can trump speed

Yet the bigger a network gets, the more DHCP servers and scopes are needed to dynamically assign, or lease, IP addresses and related IP information to network clients. The number of servers and scopes and the way the load is distributed and processed affect the speed at which networks can keep DHCP data fresh and IP leases available for use. On large networks, how efficiently DHCP lease data is documented, processed and synchronized becomes just as important as the initial matchmaking between DHCP clients and servers.

The relationship between DHCP client and server

DHCP does the hard work of handling communication between servers on a network, and client computers trying to access that network. If the series of messages between a DHCP server and a client computer would be illustrated as a conversation, it would probably look something like this.

DHCP conversation.png

Mind you, at any given moment on a large network, hundreds, or even thousands, such conversations can be occurring simultaneously. On top of that, the client computer sends its DHCPDISCOVER broadcast packet to all available servers, and all available servers can respond with a DHCPOFFER. The client is not programmed to be picky and always accepts the first offer it receives. Once they detect that their offers were not accepted, the other DHCP servers will withdraw their offers. In short, there’s a whole lot of to-and-fro action behind the scenes that is invisible to network administrators and users, but still finds its way into DHCP servers’ lease history. 

To complicate matters – or simplify it – these DHCP client-server relationships, or leases, are mostly temporary arrangements. Both parties know it will end. The server will revoke the lease once it’s expired. The client, on the other hand, can attempt to keep the lease by renewing it, or start looking for another IP address lease if the one they had had expired.

Apart from doing matchmaking between clients and servers, DHCP also ensures that each network client has a unique IP address and appropriate subnet masks. If two clients were to try and use the same IP address, neither of them would be able to communicate on the network.

These rotating relationships make the way DHCP lease data is documented, processed and synchronized so much more critical. If this is not done fast and efficiently, the whole process of dynamically assigning IP addresses can become slowed down, leaving DHCP clients, servers and ultimately network users, frustrated and ineffective.

Making DHCP management faster, leaner and fitter

Once networks run to hundreds, or thousands of DHCP scopes and servers, one needs to re-assess the way DHCP data is processed, and develop ways to improve speed and efficiency. This is exactly what Men & Mice developers set out to achieve in Version 8.3 of the Men & Mice Suite.

DHCP optimizations in Version 8.3 include:

  • Reduced network traffic, especially between the Central server and a DHCP server controller 
  • Improved database performance when processing data from a DHCP server
  • Reduced load on a DHCP server while it is being synced
