SaaS DR/BC: If You Think Cloud Data is Forever, Think Again
SaaS is quickly becoming the default tool for how we build and scale businesses. It’s cheaper and faster than ever before. However, this reliance on SaaS comes with the risk of disaster recovery. The “Shared Responsibility Model” doesn’t just govern your relationship with cloud, it actually impacts all of cloud computing. Even for SaaS, users are on the hook for protecting their own data.

Lightweight External Business Rules
Complex enterprise applications usually come with varying business logic. Such conditions and subsequent system actions, known as rules, are ever varying and demand involvement of domain specific knowledge more than technology and programming. The rules must reside outside the codebase, authored by people with core domain expertise with minimal tech knowledge.

Design Patterns for Serverless Systems
After shortly introducing design patterns at different levels of abstractions, this article will present a few patterns specifically suited to serverless systems, including the Pipes and Filters pattern and show a POC implementation using AWS EventBridge.

Introducing the KivaKit Framework
In this article, we take a brief tour of the KivaKit open source Java microservices application framework. KivaKit is a collection of mini-frameworks designed to work together. Each mini-framework is described in more detail at https://www.kivakit.org as well as on Jonathan Locke’s blog State of the Art.

Microservices — the Letter and the Spirit
Microservices to be a pattern of ‘decoupled services’ managed to get the best out of it (the underlying understanding of the pattern (‘small’ vs ‘decoupled’) forces developers to take certain design decisions that are consistent with these objectives. In this article discuss we will discuss well and poor implementations: ‘small-services’ vs ‘decoupled-services’ or ‘Letter’ vs the ‘Spirit’.

Faster Financial Software Development Using Low Code: Focusing on the Four Key Metrics
Low code/no code can help firms achieve the four key performance metrics described in the State of DevOps Reports and Accelerate, to achieve a faster pace of software development. Financial services especially stand to benefit from the trend of adopting low code/no code to drive digital transformation.

Using API-First Development and API Mocking to Break Critical Path Dependencies
Teams are using API mocking to break critical path dependencies and enable what were serial execution sequences into parallel paths. This article looks at where mocks should be used for the greatest impact and provides a model to estimate the effect of implementing API mocking and an API-first approach.

Reducing Cloud Infrastructure Complexity
Cloud computing adoption has taken the world by storm, and is accelerating unabated. According to Flexera’s annual State of the Cloud Report for 2020, 93% of respondents used multi or hybrid cloud strategies. This article examines different aspects of cloud infrastructure complexity, and approaches to mitigate it.

Overriding Sealed Methods in C#
In this article, the author demonstrates how we can change the behavior of sealed methods in C#. This can be done by understanding Operating System mechanisms and how the .NET platform generates and compiles code. The author illustrates these techniques using real-world scenarios, including the modification of the WinPAI wrapper.

Thriving in the Complexity of Software Development Using Open Sociotechnical Systems Design
The amazing progress made in technology has led to blindly following the technical imperative at the cost of the social and human dimension. Social sciences can help us create a work environment where people feel more at home and proud of what they produce. An organisation designed using open sociotechnical systems theory will be a more humane one where people are more engaged.

The Renaissance of Code Documentation: Introducing Code Walkthrough
The Continuous Documentation methodology is a useful paradigm that helps ensure that high-quality documentation is created, maintained, and readily available. Code Walkthroughs take the reader on a “walk” — visiting at least two stations in the code — describe flows and interactions, and often incorporate code snippets.

Serverless Solution to Offload Polling for Asynchronous Operation Status Using Amazon S3
This article proposes a solution to redirect the polling part to the Amazon Simple Storage Service (S3) - a highly available, scalable, and secured object storage service managed by Amazon Web Services public cloud provider (AWS). It will present a serverless implementation using AWS Lambda functions, but this is not mandatory if you want to use S3.
