Using Microservices as a Business Initiative
For microservices to work in an organization, there must be a business initiative attached to it. Questions arise among IT professionals on whether microservices are suited only for giant Web applications like Google and Facebook. However, scale is only one of the business benefits of microservices.
In today’s computing environment, innovation and speed are critical. The movement toward microservices is generated by the need to create new software that can enhance and improve a monolithic system but is separate from it. This decoupling from the legacy system provides the freedom to experiment with new approaches and rapidly iterate changes and modifications.
Traditional systems cannot move at that speed, and that may leave companies disadvantaged. At the AppSphere ’15 conference, Boris Scholl from Microsoft shared a situation they once had with a monolithic system. It had become so complex that when they added new code, the system would stop working, and it took two days for engineers to figure out why. It is too slow.
Companies are trying to decide where microservices fit in with their traditional systems. Developers used to worry simply about coding, but now with the modular approach to technology, they need to widen their view of all the technologies involved and how they work together. They now share responsibility and accountability for the project as a whole — the micro view of their direct assignment, say coding the UX; and the macro view of the final product, a home banking app for example.
Code must be monitored the minute it is deployed. The feedback loop is instantaneous. DevOps may be monitoring 50 different microservices. The data is available right away, but that means IT teams must also continuously monitor, tweak and adjust on-the-fly. It is a challenge.
The Business Case for Microservices
To leverage that asset, organizations must act quickly, changing their offerings based on a constantly evolving landscape. Legacy apps have a hard time adjusting to the new demands of the market such as mobility and the Internet of Things. Competition, especially in the form of aggressive startups that look to disrupt industries, is forcing organizations to integrate microservices architecture with their legacy systems, whether the data is in a relational database or not.
From Highly Specialized to Highly Adaptable
In the world of microservices, that approach is highly devalued. Instead, it is better for each team member to be free to operate on different parts of the application without interruption. Rather than hand off development to the next stage, the application is constantly being monitored and modified as it is being developed.
Homegrown Analytics and Monitoring Tools
For example, they built their analytics software to process huge volumes of data. How much volume are we talking about? Consider this eye-opening statistic: Networking provider Sandvine reports that just over 30 percent of the traffic on the Web during prime time are Netflix customers streaming movies.
The development of microservices is changing more than software code itself. It is making an enormous impact on how organizations think through their business processes, what products they bring to market and how they are going to support their products with customers in the marketplace.
Because of the explosion of mobile devices and the always shifting wants and needs of consumers, IT professionals have to adapt just as quickly. Microservices architecture is the vehicle in which they are creating rapid change. It is changing not only the technology but also how organizations evaluate business opportunities. On another level, it is altering the organization of talent, encouraging a culture of innovation, expanding the scope of individual responsibility and empowering smart people to take chances.
Agility and Speed are Paramount
Microservices architecture has a similar mindset as other fast development methodologies like agile software. Fast-moving Web properties like Netflix are constantly looking for greater simplicity and the ability to make changes rapidly without going through numerous committees. The code is small, and every software engineer makes production changes on an ongoing basis.
Sea Change in Software Development
This is a sea change in how traditional software development takes place. The speed at which code changes in mobile apps and modern websites is way too fast for the legacy software development system. Constantly evolving apps require a new way of thinking.
Changes in Organizations
By the 1990s, the IT department had become a critical system in every major company. If the computer systems were down for any length of time, it created bottlenecks for every department of the company.
Unfortunately, many companies still maintain the old software engineering model. However, today they are under pressure to shorten the time to bring new Web and mobile applications to consumers. Speed has become the “coin of the realm.”
Changing Culture in Traditional IT Departments
In the brave new world of microservices, department leaders must make significant changes in their organization, so developers play a bigger role in monitoring the software creation during its lifecycle, from development through to production. Interestingly, a similar development happened decades ago when data centers were so complex; Only a select few IT engineers could operate all of the disparate functions. In many cases, the staff maintaining applications were the same people that built them.
Breaking Down Barriers
It does not mean that legacy systems are being disregarded for the new kid in town. In many cases, the traditional system is doing an excellent job for the organization, so changing it without a business case would be folly.
However, the larger trends of cloud computing, mobile device adoption, and low-cost bandwidth are forever changing the way consumers buy and interact with software applications. The pace of change is dizzying, and the need for speed in application development is greater than ever before.
