The impending Digital Operational Resilience Act (DORA) aims to strengthen the IT security of financial entities such as banks, insurance companies and investment firms across Europe. The Bank of England launched an equivalent 'Operational Resilience' regime in March 2022. In this blog post, I share Monzo's smart, modern resilience strategy and look at why traditional resilience strategies put organisations at significant risk.

If you do one thing to optimise cloud carbon footprint start with your choice of region. Consider the balance between cost, environmental, security and performance considerations when it comes to choosing a cloud region consciously.

Performance improvements can be a daunting task. This post looks at some of the methods and tools available in GCP to help report the performance of your cloud application, how this can help communicate with the client and how it can enable you to narrow down performance issues in a pipeline made up of multiple services.

In this hands-on tutorial, I'll introduce Google Cloud Platform and use it to develop a simple computer vision application. We'll make the most of its user-friendly interface, great developer tools and generous free tier.

A summary of my experiences attending AWS Summit London, 2019. Highlights from talks that I found interesting and/or informative. Topics are mainly focused on high-performance computing, security and distributed architecture.

Comments systems appear across the web, I'll explain the process of using AWS' AppSync and DynamoDB to create a simple serverless version for use on a blog to provide a comment system that updates in real-time.

This post looks at how the experimental Async Hooks API can be used to support global state within AWS Lambda functions. Considering that this is an experimental API it's worth treating with caution, but it does provide an interesting potential solution to a common problem.

This month I have sat and passed the AWS Solution Architect Associate exam. Like with many things, the journey is more exciting than the destination. In this article, I share lessons and observations I made along the way.

You may have heard of "Infrastructure as Code" - but have you heard of "Infrastructure as Code as a Service"? We wanted to reliably and routinely set up hardware on demand as and when we needed it; this was our approach.

In this post, I look at how WebAssembly can be used to create serverless functions and demonstrate an AWS Lambda function written entirely in Rust.

Cloud Custodian is an open source project from Capital One. It allows you to enforce your cloud compliance rules in an automated way. One key use case of Custodian is to reduce costs by shutting down unused resources. In this post, I'll walk through setting up a Custodian and writing a policy. This will shut down EC2 instances outside working hours to save money.

The popularity of Infrastructure as Code has skyrocketed in the last few years. Such tools allow the rapid and reliable provisioning of resources straight to the cloud, saving huge amounts of time and effort in the long run. One of the most prominent of these tools is Terraform, which this post will focus on, particularly with regards to AWS.

With AWS Lambda you pay for execution duration, which means that sleeping or waiting during execution has a direct impact on your bill! This blog post takes a look at how to make AWS Lambda functions sleep, without incurring costs, via AWS Step Functions.

I describe setting up feature branch deployments with Gitlab's Review Apps and AWS Elastic Beanstalk. This gives a fairly straightforward means of setting up automated deployment of PR branches, but I discuss some issues I encountered along the way.

With an objective of building some docker images on cloud CI infrastructure I introduce one build-template sledgehammer I've been using recently, multi-stage docker builds running in docker-in-docker host container, with examples of AWS CodeBuild and Gitlab CI, and musing on other options.

AWS recently announced a couple of new container services, EKS and Fargate, and I'll give a brief overview, a "first experience" walkthrough of Fargate, and discuss when you might want to choose it.

Inspired by Colin's article on building an expenses app with the Mondo API, I wanted to create something to make use of the webhook API which fires in real-time (ish) whenever a transaction happens. In this post I'll cover subscribing to the Mondo webhook, creating the glue code as an AWS Lambda and pushing pins into the Pebble Timeline REST API.
