Folks typically suppose that implementing Site Reliability Engineering (or DevOps for that matter) will magically make all the pieces higher. Simply sprinkle slightly little bit of SRE fairy mud in your group and your companies will probably be extra dependable, extra worthwhile, and your IT, product and engineering groups will probably be completely happy.

It’s straightforward to see why individuals suppose this manner. A few of the world’s most dependable and scalable companies run with the assistance of an SRE workforce, Google being the prime instance. 

For nearly 20 years, I’ve lived and breathed operating manufacturing methods at massive scale. I had to consider tradeoffs, reliability, prices, implementing quite a lot of architectures with completely different constraints and necessities—all whereas getting paged in the midst of the night time. Extra just lately, I’ve had the privilege to leverage that have and data to assist Google Cloud clients modernize their infrastructure and functions, together with implementing an SRE apply. Whereas these learnings look completely different from group to group, there are frequent classes discovered that may impression the success of your deployment.

When issues do come up, it’s often not due to technical challenges. A stalled SRE tradition is often a enterprise course of failure—targets weren’t correctly outlined up entrance and stakeholders weren’t correctly engaged. After watching this play out repeatedly, I’ve developed some recommendation for know-how leaders about the best way to implement a profitable SRE apply. 

Earlier than you begin

Your SRE journey ought to begin properly earlier than you learn your first guide, or put in your first name to an SRE advisor. As a know-how chief inside your group, your first job is to reply a couple of key questions and collect some fundamental info. 

What drawback are you attempting to resolve? 

Most organizations will readily admit they’re not good. Maybe it’s worthwhile to reduce toil, be extra progressive, or launch software program quicker. SRE, as a framework for working massive scale methods reliably, can actually assist with these targets. To try this, it’s necessary to grasp your motivations and what gaps or wants exist in your group.

Ask your self what the group is attempting to attain from the transformation. What worries the group about reliability? For SRE to achieve success and environment friendly, it’s essential to begin with the ache. Beginning by figuring out what you are attempting to resolve is not going to simply make it easier to clear up it; it’s going to assist your group be extra centered, align the related events to a typical aim, and make it simpler to realize decision-makers’ buy-in (and way more).

When you perceive the issue you are attempting to resolve, it’s worthwhile to know when you may have “solved” it (e.g. how you’ll outline success). Setting targets is essential—in any other case, how will in case you have improved? We’ll focus on the best way to arrange metrics to assist on this self-evaluation in a later publish.

Who’re the important thing decision-makers within the group?

Regardless that implementing SRE ideas includes engineering at its core, it’s really extra of a metamorphosis course of than a technological problem. As such, it’s going to possible require procedural and cultural adjustments.

As with all enterprise transformation, it’s worthwhile to establish the related decision-makers up entrance. Who these individuals are is dependent upon the group, but it surely often consists of stakeholders from product, operations, and engineering management, although these might be named in a different way in varied organizations and may even be separated underneath a number of organizations. Figuring out these resolution makers might be particularly troublesome in a siloed group. It is very important take the time and attain out to completely different teams to establish the important thing stakeholders and influencers (it’s going to prevent plenty of time in a while). Just remember to are throwing a large sufficient web. It is very important get enter from completely different teams with completely different necessities (e.g., safety).  

On the identical time, attempt to be versatile. It’s okay in case your record of resolution makers will get up to date and fine-tuned through the course of. Like in different engineering domains, the aim is to start out easy and iterate. 

Get buy-in and construct belief

When you’ve recognized the related resolution makers, ensure you have help out of your colleagues, and the remainder of the group’s leaders. Creating an empowered tradition is essential for implementing the core ideas of SRE: a learning culture that accepts failures, that facilitates blamelessness and creates psychological security, all whereas prioritizing gradual adjustments and automation.

From my expertise, you can not drive actual change in a corporation with out widespread help and buy-in from management and decision-makers—and that’s very true for SRE.  Implementing SRE, much like DevOps, requires collaboration between completely different features within the group (product, operations and improvement). In most organizations, these features fall underneath separate management chains, every with its personal processes. For those who’re going to align these targets and procedures, management must prioritize the change. On the identical time, driving cultural change from the underside up might be more difficult and take longer than top-down mandates, and in some cultures will probably be unimaginable. In brief, main by instance and enabling the individuals within the group are essential for driving change and fostering the ‘proper’ tradition.

Keep in mind: it is a marathon, not a dash 

The journey to SRE combines a number of challenges, each from technical and human (tradition, course of, additional) views, and people are intertwined. To achieve success, management must prioritize organizational adjustments, allocating sources for engineering excellence (high quality and reliability) and fostering cultural principles like lowering silos, blamelessness and accepting failure as regular.

Align expectations! All events concerned in an SRE implementation—from product and engineering to management—might want to acknowledge that change takes effort and time, and within the quick time period—sources. Daunting as it could be, SRE’s aim is to resolve onerous issues and construct for a greater tomorrow.

And keep tuned for my subsequent publish, the place I define some tactical concerns for groups which might be early on their SRE journey, from figuring out the best groups to start out with, enablement and constructing group.
