Hi there 👋

If you work with US government entities or corporations in regulated markets the subject of FIPS compliance may come up, especially in the context of FedRAMP authorization. FIPS 140-2 and FIPS 140-3 are a set of cryptographic standards that your application may need to adhere to dictating the appropriate ciphers or cryptographic functions that are in use. It can take a lot of effort to run a completely FIPS compliant architecture, but for application developers, the bottom line is that any code that uses cryptographic operations to secure customer data must use FIPS certified cryptographic libraries....

Most new applications are built as a single codebase and deployed as a monolith until product-market fit or the need for additional scale is required. Such monolithic applications are easy to write and maintain, and allow you to iterate quickly when there are a smaller number of users and the traffic is low. However, as traffic increases you will need to scale the application to handle the increase in load. One framework for scaling is the “Scale Cube” describe by AKF partners....

eBPF is a technology allowing you to dynamically program the kernel using a virtual machine approach. Several development frameworks exist, with the top choice for Rust developers being Aya. Because of the deep integration between eBPF and the Linux kernel, it can be challenging to create a local development environment that works across different development machines. To date, I’ve taken to developing eBPF programs on EC2 instances using the AWS Cloud9 development environment....

One of the larger hurdles to climb when becoming FedRamp moderate is encrypting all data in transit using FIPS validated encryption modules. This article describes one approach to satisfying this requirement for anyone running a Kubernetes cluster on AWS. For those lucky souls who are unfamiliar with FIPS, it stands for Federal Information Processing Standard (FIPS), which is a joint US and Canadian government standard that specifies the security requirements for cryptographic modules that protect sensitive information....

This article provides guide to the different developer tools available for writing eBPF programs, covering the core tools BCC, bpftrace, ebpf-go, and libbpf. These tools satisfy a different use case depending on whether you are trying to use eBPF for running analysis scripts, or full-fledged programs, in what programming language you wish to use, and the maturity and feature parity with the most recent eBPF features in the Linux kernel....

A common pattern when scaling a SaaS application is to deploy your stack to multiple regions across the globe. Deploying to multiple regions helps distribute the application and data closer to the user, and isolates infrastructure in case of an outage in a single region. If your application is deployed in this configuration, you have the new problem of routing users to the correct region based on their tenancy or geography....

A short tagline from the book Learning eBPF describes eBPF as a revolutionary kernel technology that allows developers to write custom code that can be loaded into the kernel dynamically, changing the way the kernel behaves. The key word in this phrase is dynamically. eBPF allows you to write custom code that changes the way the kernel behaves without having to implement a kernel module or integrate your code directly into the kernel....

DynamoDB provides built-in support for cross regional data replication using a solution AWS calls global tables. This article shows how to build and run an application in Kubernetes that uses global tables to replicate data between regions. In the event of a regional disaster, a secondary Kubernetes cluster in a secondary region has all the data from DynamoDB replicated locally to continue operation. How global tables work A DynamoDB global table is a set of multiple replica tables....

Disaster events are one of the biggest challenges that a software organization can face. Natural disasters like earthquakes or floods, technical failures such as power or network loss, and human actions such as unauthorized attacks can disable an entire fleet of systems, leading to complete failure for a business. To deal with disaster scenarios requires a proactive approach to prepare and recover from failure. One of the key benefits of running in the cloud is how easy it is to run workloads in multiple regions....

Check out the project on Github. I recently published a new project for repeatable filesystem benchmarking. This code is based on the benchmarks available in the AWS Mountpoint-s3 project and the Flexible I/O Tester, made into a more general purpose utility for benchmarking arbitrary filesystems. The benchmark consists of a mix of read and write workloads, each run for ten iterations. The average result of the ten iterations is reported as the final result of the benchmark....
