Software engineering organizations of all sizes are responsible for building and maintaining reliable software. But, for Software Engineering teams, DevOps teams, and SRE teams to successfully deliver reliable software, they need the right tools available throughout the software development lifecycle. If you’re looking for tools for building reliable software,

In the early days of Google, a lot of users were asking for 30 results on the first page of search results. So after long deliberation, Marissa Mayer, then the Product Manager for google.com, decided to run the A/B test for ten vs 30 results. When the results came in, they were in for a surprise.

Change is the only constant in a cloud environment. The number of microservices is constantly growing and each of these is being deployed several times a day or week, all hosted on ephemeral servers. A typical customer request depends on at least 3 internal and 1 external service. It’s

How to get the most out of your logs!

Quick primer into microservices architecture and the importance of tracking dependencies

How do you set Latency based alerts? The most common measurement is a percentile-based expression like: 95% of the requests must complete within 350ms. But is it as simple?

Thanks to Service Level Objectives (SLOs), your teams have a numerical threshold for system availability, so everyone has a clear vision of what keeps the users and the business happy.

A monorepo is a single version control repository that holds all the code, configuration files, and components required for your project (including services like search) and it’s how most projects start. However, as a project grows, there is debate as to whether the project's code should be split into

Service Level Objectives or SLOs serve as an objective measure of your system's performance. And when designed well, SLOs can help you direct engineering efforts effectively. It does not matter whether you're working in a startup or a tech giant; there is always a natural tension between the speed of

As with any operating system, it’s not uncommon to encounter issues while running Linux and associated applications. This is especially true while using closed-source programs since granular code inspection isn’t possible.

What is Saturation and why should you think about it as an SLO? Saturation can be understood as the load on your network and server resources.

We've all been woken up with that dreaded Slack notification at ungodly hours only to realise that the alert was all smoke and no fire. The perfect recipe for dread and alert fatigue.

Gone are the days of yore when we named are our servers Etsy, Betsy, and Momo, fed them fish, and cleaned their poop.

Observability is not just about being able to ask questions to your systems. It's also about getting those answers in minutes and not hours.

While using a Terraform lifecycle rule, what do you do when you get a canned response from a security group?

A Terraform lifecycle rule in the right place can help prevent a deadlock. But the same lifecycle rule in the wrong place?

How you can run into an unplanned downtime while making a seemingly harmless change of renaming an AWS security group through Terraform?

I gave a talk at react.geekle.us today about improving reliability of our React app. Here are slides of that talk. Here is transcript of the talk. Hello all, my name is Prathamesh Sonpatki. I work at Last9 building a world class operational intelligence platform for SREs. The Last9

I completed one year at Last9 today. When I joined Last9 on April 20th 2020 last year, I was unsure how it will pan out. I only knew Nishant and Piyush - founders of Last9 from Pune tech community. But I had never worked with them before. Some of the

We ran a poll on Twitter“Do you care about the quality of your infrastructure code?”And on RedditThat’s an approximate and staggering 60–30–10 split. What do you think will the response be if the poll was — “Do you care about the quality of your product code?

What are SLOs and how do you define them. We usually set SLOs that might not accurately define what the requirements are. Here's a look at SLOs That Lie! SLO is an acronym for Service Level Objective. But before I explain SLO, you need one more acronym SLI (Service Level

What are P90, P95, and P99 latency? Why are they incorrect P99 of the times? Latency is for a unit of time and the preferred aggregate is percentile.

Chef or Ansible? Terraform or Pulumi? Python or Ruby? Last9 or Last9? What if we told you that the mindset of building new tools has an age old link to the story of a horse who could do arithmetic?
