Trends in Software Architecture to Watch and Implement?

Trends in Software Architecture to Watch and Implement?

With changes to the methodologies on how we develop our software, it only makes sense to expect a greater focus on evolutionary architecture and microservices data distribution.  The essence of creating and using evolutionary architecture is to make small changes, and put in feedback loops that allow everyone to learn from how the system is developing. The rise of Continuous Delivery has been a crucial enabling factor in making evolutionary architecture practical.

You must look at 2017 for some of the evolution changes in software architecture, last year was extremely busy.  Even the tried and true C++ got a revamp in 2017, this is a language that has only seen 3 updates since 1998!  It is very important to review the major changes in the past to get a full understanding on what is coming!

Are the experts wrong?  

According to Mark Richards; “Evolutionary architecture and automation of architectural governance and analysis are going to be a major focus for software firms in 2018,” Mark is author of Software Architecture Patterns a knowledge leader in software trends.

This isn’t a case to move all your apps to microservices—although microservices do qualify as an evolutionary architecture. It’s about switching your focus on the development of architectures that can handle significant change over time.

To qualify to be called an evolutionary architecture, you must have the following qualities:

  • Highly modular and easy to couple with other systems
  • Organization architecture focused around business capabilities
  • Have the ability to conduct operationally inexpensive experiment

Serverless architecture will continue to grow

Many of the top leaders in software development have concluded that serverless will continue to gain strength with developers and their respective companies.  With the ability to scale capacity and controlled cost, Functions as a service (FaaS) will allow developers to create applications and services much more effectively.

Enterprise development activities will increase their interest in FaaS resources.  Right now, AWS Lambda is the go-to serverless platform for most developers. Although serverless technology is still in its infancy, AWS will continue to dominate the serverless space for 2018, just as it dominates in other cloud infrastructure areas.

 

Microservices Technology is here to stay

Designing applications that can be more scalable and are highly independent and deployable is what Microservice architecture was built to do. Build around the business capabilities, each service can be run as its own process. With the ability to have all the services written in different programming languages and using different data storage technologies.  This flexibility means that many teams can manage the applications and products.

The Advantages are many with this microservice architecture:

  • Each microservice is small and it is therefore easier for the developer to understand
  • As mentioned before, each service can be deployed independently so it is easier to deploy new versions of services on a regular base
  • It is much more scalable and each service’s management can be assigned to a different team and can be worked on at different times and independently

Docker Services and the platform is not just for legacy systems

Docker is an open source platform for developers to use. The idea is to create, deploy, and run applications, on laptops, data center, or on the cloud, by using containers. Why is using containers great? The main reason is that it enables us to package an app with all the parts that is needs and then ship it all as one and this means that the app will run on any Linux machine, even if it has customized settings. Using Docker increases performance and reduces the size of the app.

Reactive programming may outstretch scalability of other options

Not very well know due to the fact that it was poorly documented, Reactive programming didn’t have the jumping board some other technologies had. With more developers gaining knowledge of its interactive and highly scalable benefits, it is gaining. Reactive programming is basically based on data flows and the propagation of change.

Resilient software design is about the long term

Long term software product strategy should include a process for achieving resiliency, using a structured approach over the lifetime of an application, from design and implementation to deployment and operations.

There are many that confuse resilient systems to failsafe systems. But, resilient systems don’t fail, they recover back to the original state they were in. Based on a survey done to developers, we can see that resilient software design gained popularity with 60% of the respondents interested in it compared to 54.5% last year.

In a distributed system, failures will happen. Hardware can fail. The network can have transient failures. Not very often will an entire service or region experience a disruption, but even those must be planned for.  Building a reliable application in the cloud is different than building a reliable application in an enterprise setting.

So, what is the best plan of action? 

Those are not the only tech trends in 2018 in the software industry, but they are the main ones we talk about in our environment. It’s an environment that changes and grows quite fast and it’s important to stay up to date to not be left behind. If you have any other tech trends you think could be a nice add up to the list don’t hesitate to add it in the comment section!
