The concept of service level objectives (SLOs) and error budgets have been key to this transformation, as SLOs shape an organization’s ability to make data-oriented decisions around reliability. (Read here for a definition of SLOs and how they transformed Evernote.). Today, the Twitter team has invested in centralized tooling to measure, track, and visualize SLOs and their corresponding error budgets.

To be effective, service level indicators must be relevant to the users’ needs and experience. By consolidating a number of internal metrics into one indicator that reflects the typical use of the service, we can ensure that meeting our SLO means keeping users happy. A good way to think about this is by looking at the user’s experience or journey.

Service Level Objectives, or SLOs, are an internal goal for the essential metrics of a service, such as uptime or response speed. We’re probably familiar with this definition, but what is the value of setting these goals?

A remarkable milestone for any company’s site reliability engineering (SRE) is five 9s availability. That’s less than 30 seconds of service unavailability per month! Exactly what Twilio has accomplished. Tyler Wells, the Director of Engineering at Twilio, shares the key building blocks of getting to five 9s.

SLAs and SLOs are both reliability metrics based on SLIs. Here we explain their differences and the importance of each for reliability teams.

Service level management requires airtight processes to ensure SLAs are on track and to catch any issues beforehand, while following these ITIL best practices.

A "Service Level Objective" (SLO) is an internal target that measures how well a service is performing. Here's how they relate to SLAs, SLIs, and error budgets.

A post-incident review is an evaluation of the incident response process. The goal is to have clear actions to improve the process and prevent further incidents.

Something big happened at Blameless this month — our “Postmortem” feature was updated to its new name, “Retrospective”. To the naysayer, I suppose you’re thinking, This seems trivial. Different teams call it different names anyway, so why bother making the change? First let me say, thank you for reading our blog and I hope you finish this one through to the end. Now, allow me to explain our reasoning and why we’re excited about this update.

What is root cause analysis and contributing factor analysis? Let's take a look at the best practices.

In this post, we’ll construct a basic reliability model and show you how to create one for your own organization.

For many SREs, Google’s 99.999% availability seems like an untouchable dream. If anything, getting out of pager hell is already worth celebrating with all your coworkers, friends, and family. How can you get to a stage where you have time to proactively prevent incidents, and enter a mental state of calm and control?

Availability is the percentage of time a system is available to users, while reliability is likelihood that the system will meet a certain level of performance.

Wondering about software reliability metrics? We explain the important metrics you need to track.

In this blog post, we’ll look at how to design services that can remain reliable while scaling, balance reliability and development velocity, respond to incidents using best practices, and build trust when incidents occur through good communication.

In a recent fireside chat with Mohan Bhatkar, Head of Engineering for the Customer Reliability Platform at Mercari, Inc. sat down with Blameless Co-Founder Ashar Rizqi. They talked about scaling while avoiding silos, exciting day-to-day challenges, instilling a culture of empowerment, and more. Here are their top insights and the lightly edited transcript of their conversation.

In this blog post, we’ll break down what software reliability means. We’ll look at how the reliability of your software is perceived, how teams operate to improve reliability, and how to contextualize reliability with customer happiness and cultural lessons.

Here we break down reliability in terms of other metrics within reliability engineering: availability and maintainability.

Here are some helpful steps to take to improve reliability of a system. We'll use a development project as an example.

What makes reliability engineering so important? In this blog, we’ll look at three big benefits of investing in reliability and explain how you can get started on your journey to reliability excellence.

We had the privilege of interviewing Brian Brophy, Sr. Staff SRE, Carrie Fernandez, Head of Site Reliability Engineering, JP Doherty, Engineering Manager, and Zachary Kiel, Sr. Staff SRE to learn about how SRE is practiced at Twitter.

It’s astonishing that despite the tremendous time we spend working on our systems, we seem to have very little control over them. If we can’t predict where the next incidents will come from, then we will be forever stuck in a reactive cycle of repair. An analogous example is the famous fable of the Three Little Pigs.

Whether you are a hiring manager or an SRE job candidate, there are certain questions you should be prepared to ask or respond to. Find out what they are here.

SRE is a practice that creates a bridge between operations and development. We discuss the roles and responsibilities of a site reliability engineer.

Development velocity is a measurement of how much work a software team can complete, based on similar work completed in previous iterations

Being affected by SRE toil? We define what SRE toil is, discuss how it can adversely affect your productivity, and tell you the best techniques to reduce it.

Wondering about severity levels? We explain what incident severity levels are, how to classify them, and how they will affect your incident management process.

Alert fatigue is the phenomenon of employees becoming desensitized to alert messages because of the overwhelming volume and number of false positives received.

Wondering about Cloud-Native Development? We explain what cloud-native development is and how it can help build fast and reliable applications.

As organizations progress in their reliability journey, they may build a dedicated team of site reliability engineers. This team can be structured in two major ways: a distributed model, where SREs are embedded in each project team, providing guidance and support for that team; and a centralized model, where one team provides infrastructure and processes for the entire organization. Most structures will be some combination of these ideas, with some SREs focusing on specific projects and other SRE projects completed as an SRE team.

As responding to incidents becomes both more complex and important, how do you leverage tools to bridge the gap?

The integration between Blameless and Microsoft Teams is significant for our customers, because it enhances their main line of communication during the most pressing moments of incident response. Directly from Microsoft Teams, an on-call engineer initiates an incident, notifies stakeholders, and orchestrates rapid response, all while automatically collecting each event or “touch” that adds value to the retrospective (postmortem) for learning.

Distributed software systems have many points of failure. Can the process of chaos engineering help identify problems and gauge resiliency?

Blameless released a new integration to ServiceNow’s incident management ticketing solution. If you are a DevOps team moving towards SRE, this is worth a look.
