Burst SMS got a big upgrade and no one noticed (that's a good thing)

A lot of work went into making sure you saw… absolutely nothing.

We added 12 servers, upgraded over 100 microservices, and optimised over half a million lines of code. All this with no downtime and zero issues.

How did we achieve this?

Our company is growing very quickly, and we are now responsible for sending millions of messages per day. We take this responsibility very seriously. We know that in the instantaneous world of business SMS messaging, even minutes of disruption can cause you headaches.

To ensure that the transition was seamless, our highly talented team of engineers meticulously planned every step over two months. Ultimately, we deployed a mammoth release to our core infrastructure without so much as a blip.

What did we do?

We started by spinning up a parallel environment, identical to our live systems. We then optimised and improved the code in the new environment. After meticulous testing, we deployed it.

Our software engineers scrutinised over 500,000 lines of code and categorised the code into over 100 microservices. Each one was either updated or deprecated.

Then, we decommissioned our twelve ageing servers and deployed brand new ones in their place, with double the memory and processing power.

What’s in it for you?

Even more speed. You will notice a speed performance boost in page load times at your fingertips, meaning you can get more done in less time. You will also see a greater throughput of the system.

These changes ensure that our online SMS service continues to be reliable and future-proof, and it makes it easier to add new and powerful features. For that, stay tuned!
