How to Jump From Cloud to Cloud

In 2010, when Netflix was still early into its shift from DVD rentals to online movies and shows, it started using Amazon.com’s data centers. Video streaming’s popularity was growing fast, and Amazon Web Services, the retailer’s cloud computing division, had the capacity to handle the load. Now that Netflix streams 100 million-plus hours of video every day, it’s sticking with Amazon partly because of Amazon’s scale and features, and partly because switching vendors “would be a significant multiyear effort,†…

The Growing Waves In the Linux Ecosystem: Two Perspectives

foxtech-logoEditors’ Note: This article is sponsored and written by Fox Technologies.

In the early 1990s, the Open Software Foundation formed a committee to select and standardize a new Management Platform Toolset for and from the UNIX ecosystem. After much soul searching over a few months, the OSF Management Platform never arrived. One member of the committee, from the team that invented The Newcastle Connection (1980s *NIX history, go Google it) made a compelling presentation explaining why they failed. Presenting from two very different perspectives, he had the audience full of system administrators rolling with laughter at the answers drawn from an OSF selection team executive and a sysadmin working in the trenches.

The Latest Linux Wave

Since you’re reading this article, you will have your own perspective on the Linux ecosystem. A lot has changed even in the last year; we’re experiencing a massive wave of Linux take-on via virtualization and the cloud as accelerators.  New companies are growing from 10 servers to 10,000 instances in two or three years. For older customers, however, we’re also living with a legacy of old infrastructure decisions made (for some) decades ago, some pre-Linux.

In the middle of all this is you — that rare and finite resource, the Linux admins. You may be a manager (who was an admin grunt when decisions were made years ago), or you may be a grunt on the front line right now.  In the same tone as that meeting in the early 1990s, let’s apply those two viewpoints to the following statistics:

The good news: Linux is on the up and moving like a freight train. 87% or organizations added Linux servers this year. About the same will add more Linux next year. Windows deployment has fallen from 46% to 26%

A manager might say: The organization took a strategic decision last year to standardize on Open Systems Infrastructure to manage our asset and cost base more efficiently, streamlining technical and operational silos.

A sysadmin might say: Let’s be honest, we’re migrating to Linux VMs and Linux in the cloud to save money. The business may have LIKED Windows server in the past, but Microsoft’s licensing mechanisms seem to be purposely designed not to work in virtualized and cloud infrastructures, unless the business has gone Azure. And if that had happened I wouldn’t be here.  We’re already expected to support twice as many server instances as we did before, and to be honest expect to see that will rise again without our team growing at all, so we’re going to need more automation.

And Its Squeaky Wheels

A worldwide, year-long survey of what people are ACTUALLY doing with their infrastructure is just moving into its second year. FoxT will be presenting their first year results formally over the next few weeks, obviously tied into their sales and marketing efforts.

Some valid commentary that can be made on some of the initial raw data, both as a manager and a sys admin. Beyond the marketing and positive news of new companies and projects going live in the ecosystem worldwide, there are some acerbic and wry grumblings over a few (Ed: A few??) beers and margaritas at Linux user group meetings. Your admins are talking, and it’s not all good news.

Here are four quick samples of the annoying squeaky wheels we’re dealing with as the ecosystem grows.

1. 70% of organizations worldwide use LDAPS and Kerberos for secure authentication

Manager: It is encouraging that industry best-practice is being utilised by the majority of the ecosystem for LDAP based (48%) and Kerberos (21%) authentication, providing centralization and control of user and session access.

Sysadmin: A couple of things here

  • What the survey also says is 10% of larger enterprises are still using NIS and NIS+. Mainly larger, global companies (many web-facing) still have not migrated away from NIS, even though it has been End-Of-Lifed a while ago.  I follow the news, if those servers are already penetrated, our host, group and user information is zipping around in the clear. Does the Board appreciate that?
  • If I’m running or migrating into a G-Cloud, which requires complete separation between infrastructure layers then LDAP and Kerberos break the rules because they both have to be pervasive for authentication on all network layers for the support teams to work. We have to start bridging networks and adding strange proxies, breaking the G-Cloud architectural model.

2. 50% still manage Linux privilege escalation with Internally Developed Solutions

Manager: We’re making effective use of existing toolsets to ensure we can audit privileged escalation, and show evidence to our System Owners and Auditors. Extending some of our existing Configuration Management and Operational reporting tools we have saved the business from investing in a commercial product, or purchasing an additional service from our business partners.

Sysadmin: Internal, as in non-standard, maybe non-best-practice (I can’t remember the last time we updated our rules), untrained (in the unlikely event we do get another or have to replace a team member), and badly documented. Most damningly, it’s unaudited and violating segregation of duties.  My team maintains and supports this stuff, and it’s my team’s activities that are being monitored. Do you see the problem?

3. Over half of organizations worldwide provision and deprovision their Linux servers manually

Manager: This is scary – I was pretty shocked when I saw this result. I see 44% use tools to enable automatic account and group provisioning which is encouraging, we interact with new customers and projects all the time recommending best practice to use automation or IAM tools to enable this. Obviously, from these results we still have a long way to go; we need to keep evangelising, and especially with smaller customers.

Sysadmin: That’s a huge number of guys and girls still doing essential operational tasks to make sure critical applications are setup properly. Not the most inspiring part of my day, let me tell you, and probably assigned to the most junior team member on shift, who might miss something.   Remember that NIS directory we turned off last year because we were told to by the auditors? Now we now have no control of UID/GID consistency.  If we do add automation, it may take months to fix that system by system before we get any benefits; you’re going to see that as a cost, not an efficiency saving.

4. 71% or organizations worldwide plan to use Red Hat Enterprise, Ubuntu Enterprise, or SUSE Enterprise Linux in the next year

Manager: The Linux ecosystem is maturing, and the positive trend of customers migrating to Enterprise Linux editions for rollout into their production infrastructures shows this. Even with an exploding Linux installed base, organizations are seeking business-level assurance provided by the maintenance and SLAs provided by Enterprise Editions from the vendors.

Sysadmin: Ok, we used (CentOS/Debian/openSUSE) as a startup, and this move makes a lot of sense, change and patch management integrated with automation is v. good.   

Boss, I need to take you out for a beer and a chat. Looking at this, there is going to be a lot of market competition for trained staff. Let’s talk about training and certification. We’re going to need to formally train and certify a chunk of the admin team before we do this to meet the vendor’s minimum SLA requirements. Off the cuff, that will take an ongoing FTE of two out of support for a few months. Do you have the budget to hire some consultants to cover that?

And talking about budget, about my next review…

What do you think? Heard something similar? Obviously, we’ve all seen the positive strides Linux has made in market share worldwide, and it is a nice feeling to be part of a growing trade that values our skills. That has its own pressures, especially on staffing and day-to-day operations. FoxT is an infosecurity company, so many of their questions are in that area, however I’m sure similar grumbles exist in configuration management, operational monitoring, and deployment.
