By: Rajiv Shringi , Oleksii Tkachuk , Kartik Sathyanarayanan Introduction In our previous blog post, we introduced Netflix’s TimeSeries Abstraction , a distributed service designed to store and query large volumes of temporal event data with low millisecond latencies. Additionally, we employ a bucketing strategy to prevent wide partitions.

A look at the roles of architect and strategist, and how they help develop successful technology strategies for business. I should start by saying this section does not offer a treatise on how to do architecture. It's a given that we must design a system, including a local software architecture, that actually runs, that is "solid."

Over the past few years I have focused much of my learning and work choices around learning about the design of sociotechnical systems?—?how how to design software architectures and organise teams around them. As part of good design, we should consider the effects of changing all of these variables.

There are a few qualities that differentiate average from high performing software engineering organisations. I believe that attitude towards the design of code and architecture is one of them. Both valuing design and striving for continuous delivery are necessary. So we need to make it part of everything we do.

Stream processing One approach to such a challenging scenario is stream processing, a computing paradigm and software architectural style for data-intensive software systems that emerged to cope with requirements for near real-time processing of massive amounts of data. This significantly increases event latency.

The microservices era has been good for software architecture. A domain service builds on the basic definition of a microservice: it’s a loosely-coupled, independently deployable element of software architecture which is owned by a single team. A common question in designing a domain is “how big should a domain be?”

Domain-Driven Design is an approach to designing systems, usually software, that emphasises creating a common language between domain experts and system builders. This is normal, embrace the fuzziness and apply design thinking. The elements in Simon Wardley’s Strategy cycle are much more usable in my opinion.

Mapping out your business’s domain landscape has many benefits: knowledge sharing, generating product ideas, providing the foundation for software architecture, aligning on requirements, but a common challenge is… “where do we start?” The high-level structure is not design structure (e.g. Q: What is a domain landscape?

Perhaps led by strong managers, they will fight vehemently for their work to be prioritised and software systems to be designed to their needs. This organisational pattern can be mirrored in the software architecture, emphasising the sociotechnical nature of systems. These concepts also apply to distributed architectures.

Typically, there’s a period where modernization is discussed as the pains of legacy systems and/or ways of working are noticed and become ever more prominent, blocking the business strategy. Some companies talk about modernizing for years before they make a serious commitment. We informally call this the Noticing stage.

One of the key decisions we need to make in software architecture and in our organisations is when and where to create shared services and organise teams to build them.

How will you design the most effective architecture which supports short-term goals and long-term evolution?
