Avoid data duplication

text to describe the image

Recently I experienced something that you usually hear about when going through resources around cloud and distributed systems, which is everything fails, and you need to plan for it. This doesn’t just mean infrastructure failure but also software failure. Now, if you ever went through any of the AWS messaging services documentation like SNS and SQS, I am sure you have read somewhere in the documentation that they ‘promise’ at least one message delivery and they don’t guarantee exactly one.…

Those totals grow by more than 3 million documents (3 terabytes) a day. Think about an insurance claim for an auto accident. You have the photos of the damage, the estimate of the repair and the payment for…

Improving API Performance with HTTP Keepalive by Clete Blackwell II
Optimizing response time by reducing unnecessary connection reestablishment

Improving API Performance with HTTP Keepalive

Performance of business functionality is important. To keep this at the forefront, modern business functionality is backed by one or more customer-facing APIs (Application Programming Interfaces) which are often backed by a series of microservices. Any amount of unnecessary response time in a deeply-nested service can cause slow performance to customers, potentially creating inefficiencies and diminishing customer satisfaction.

Embracing Chaos by Ranjita Sahu
A Product Team's Journey

Perspectives

On a frigid night in late February 2012, I received a call for an emergency production issue. One of the critical batch jobs that processes data for the next day’s business had failed.

My then-product manager got us pizzas, coffee, and hot chocolate to cheer up the room, and the team spent the next couple hours pushing an emergency fix to production. Over the past decade, system failure analysis and maintenance…
