This guide will help you better engage in business-level conversations about Site Reliability Engineering with key stakeholders. It is part of the SRE Digital Transformation series exploring how to integrate SRE into your organization.
Introduction
Site Reliability Engineering (SRE) is a powerful tool for achieving high software performance and reliability in enterprises, as well as managing cloud costs.
As Sriram Gollipalli of Agilent Technologies explains:
In simpler terms, SRE allows developers to continuously deploy new features while ensuring that the systems running the software remain stable and reliable for customers.
This guide takes a leadership perspective on SRE and provides clarity on its rationale for enterprise cloud deployments.
Additionally, it analyzes how SRE traits converge and diverge from traditional enterprise IT culture.
What is Site Reliability Engineering?
You likely possess a solid understanding of the answer, but if not, I suggest reviewing the comprehensive Site Reliability 101 guide.
First, allow me to clarify the definition to ensure we are aligned before proceeding further.
Technical definition: Site Reliability Engineering is the application of software engineering principles to improve the operability of software in production.
In plain English: SRE is what you get when you hire and train software engineers to constantly improve your software operations.
Business translation: If you manage your own software services in the cloud, hiring SREs can guarantee meeting uptime and performance SLAs.
ℹ️ The role of a Site Reliability Engineer is executed by individuals who implement the principles of Site Reliability Engineering. It is important to note that both the role and function share the acronym SRE.
Site Reliability Engineering is a powerful risk mitigation practice that effectively reduces the likelihood and severity of issues that impact SLAs.
These issues can include network outages, product feature issues, data loss, revenue loss, and security risks.
Although SREs don’t develop user-facing software with features, they have experience in software development earlier in their career.
SREs combine two skills that are typically considered mutually exclusive: operations skills, such as a deep understanding of systems like networks and platforms, and software development skills, to code up creative solutions to problems.
Using both skill sets, SREs create innovative software solutions to solve operational issues.
The most experienced SREs operate like SEAL Teams, solving complex issues in murky situations that regular forces can’t resolve with a process-oriented skillset. Senior SREs expertly code up tools and fixes to increase system resilience, striking a balance between a generalist (system-wide) perspective and specialist (infrastructure code) know-how.
In a single week, Site Reliability Engineers can:
- Undertake incident response with the goal of identifying root-cause issues
- Work on projects to develop tools and fixes that prevent and resolve complex issues
- Participate in architecture reviews to identify opportunities to increase system resilience.
But will leadership truly benefit from buying into SRE?
In the next few lines, I will confidently save you time and money, potentially saving your organization thousands or even millions of dollars.
Pay close attention to the following:
- Is there a significant financial cost associated with downtime or poor performance?
- Are your operations staff encountering infrastructure roadblocks due to a lack of coding skills?
- Is your infrastructure struggling to keep up with demand?
- Are your developers producing code with high technical debt?
- Is system architecture an afterthought to feature delivery?
- Are your developers taking risks with DIY push-to-production practices?
- Do critical systems appear to be increasingly fragile?
If you answered “yes” to the first question and one or more additional questions, continue reading.
If not, you may wish to save your budget and take your developers on an off-site retreat instead.
Summary of benefits of SRE for enterprise
- Savings potential of $10,000-$100,000+/month on cloud computing costs – impress your CFO with cost savings.
- Increase your ability to integrate security into applications and services – impress your CISO with enhanced security measures.
- Improve developer and operations interaction – maximize ROI on your “DevOps initiative” investment.
- Increase uptime of your production systems – ensure uninterrupted revenue streams.
- Increase the availability of services to enhance accessibility for users.
How do SREs help reduce cloud costs?
Cost has become a top factor in enterprise for determining ROI from cloud investments.
When it comes to cloud computing, there are many factors that can affect the cost of implementation.
We will explore a few ways SREs can help with the cost situation.
One way that SRE can help reduce costs is through more effective capacity planning.
By analyzing usage patterns and predicting future demand, SRE teams can ensure that resources are provisioned in the most efficient manner possible, avoiding unnecessary expenses and waste.
Another important factor is cost computing.
SRE teams can use advanced analytics and monitoring tools to gain greater visibility into the cost structure of their cloud infrastructure, identifying areas where optimizations can be made and expenses can be reduced.
Overall, the SRE approach can be a powerful tool for reducing the cost of cloud computing while improving performance and reliability.
By focusing on continuous improvement and automation, businesses can achieve greater efficiency and cost savings over time.
