Are Developers finally starting to Understand DevOps?

devops-blog

Software developers remain a curious and opinionated bunch. Over the last few decades they tend to adapt slowly to new methodologies, with DevOps offering little exception to this golden rule. A recent survey reveals things are finally beginning to change, as it shows application engineers beginning to actually “get” DevOps.

Of course, we recently wrote about network administrators feeling DevOps is all about the “Dev” in the first place. What follows is an analysis of the survey to see what these changing opinions mean for the process of software engineering. Perhaps you might gain an insight or two to help your own team’s project work?

Survey says DevOps makes Software Development Faster

Most organizations implementing DevOps do so in the hopes of making their software development process faster and more efficient. A survey of software engineers, CTOs, and IT pros by application maker, GitLab, notes that these wishes appear to be coming true. News about the survey appeared last month on the Developer Tech website.

According to the GitLab study, two-thirds of those polled feel DevOps greatly improves the speed of the software development process. This 65 percent moves upwards to 81 percent when only taking into account the opinion of managers. 29 percent of those surveyed plan new DevOps investments in the current year.

The best shops using the methodology are able to spend at least half of their workday actually writing code. Changes get deployed on demand. In short, these top organizations are twice as productive as those whose DevOps implementation is either immature or nonexistent.

Challenges to Efficient Application Engineering Remain

In their survey, GitLab highlighted a few challenges to the software development process. Two-thirds of the respondents noted the lack of clear direction on application engineering projects. Slightly over half mentioned the need for rework and unexpected scope creep, while 31 percent felt unrealistic expectations hampered their efforts.

Leveraging automated processes to improve efficiency is a high priority at 60 percent of the surveyed organizations. Around 90 percent of those companies are currently using Agile, DevOps, or a mixture of both. 16 percent are still using the venerable Waterfall methodology for some or all of their development work.

Continuous testing also plays an important role in the ultimate success of any company’s DevOps adoption, a concept highlighted by Razi Siddiqui, SVP and CIO at GCi Technologies. “It’s a key indicator that your DevOps/agile practice is mature, and your QA strategy must take into account that 100% test automation is not practical – nor is it possible,” said Siddiqui.

Sid Sijbrandij, CEO and co-founder of GitLab, commented on their survey conclusions. “The survey reveals software professionals finally see the need for DevOps in their workflow and are beginning to adapt their workstyle in order to make this a reality. Despite the progress in the shift in mindset, current DevOps practices are not cutting it. Instead of a single application that accomplishes the goals of both Dev and Ops, many glue together the tools for the two departments, which has proven to be an ineffective means for collaboration,” said Sijbrandij.

It definitely appears that any enterprise software development not using DevOps runs the risk of being left behind in today’s business landscape. Thanks for reading this edition of the Betica Blog. Keep returning for additional insights on the wide world of software development.

PostgreSQL is a Hot Database Choice yet Again

It seems the venerable PostgreSQL database is garnering a new wave of buzz across the IT industry. Maybe our series of articles on Postgres earlier this year helped contribute to this newfound hipness? Probably not, but modern tech organizations hoping for a cheaper alternative to Oracle while still getting support for NoSQL consider it to be a worthy option.

Let’s look more closely at some of the reasons why PostgreSQL remains one of the hottest databases – relational or not – on the market. Perhaps it makes sense for your team’s next data-centric web or desktop application?

Postgres is actually growing in Popularity!?

PostgreSQL’s increase in popularity caught the attention of InfoWorld magazine, who recently talked about the database’s hot factor earlier this month. In fact, Postgres now ranks as the 4th most popular database in the industry, according to a study by DB-Engines. Not surprisingly, the only three DBs ranked higher are Oracle, MySQL, and SQL Server.

The reasons for the growing popularity of Postgres – especially with younger developers – are numerous. InfoWorld’s writer, Matt Asay notes the improved performance brought by the support for JSON included in PostgreSQL 9.2 and boosted in version 9.4. Another important reason involves programmers growing tired of trying to fit even hipper NoSQL options like MongoDB into solution where a relational database makes the most sense.

Ultimately, in a situation when an old-school DB works best, PostgreSQL’s open source nature is simply more cost effective than Oracle or SQL Server. In fact, Postgres first earned its mojo as a cheaper alternative to Oracle. Still, could this old school database scale fast enough for use in modern web applications?

PostgreSQL and its newfound Scalability

The ubiquitous nature of social networks like Facebook and Twitter puts the onus on modern web applications to be extremely scalable. Most RDBMS options generally provide poor scalability, as did Postgres for most of its existence. Asay notes the introduction of Citus, an extension for PostgreSQL, provides a level of scalability rivaling many of the popular NoSQL databases.

Citus supports Postgres instances across multiple nodes, while providing a distributed model for transactions and SQL queries. These features give this veteran relational database the parallelism required for a massively scalable application able to compete in today’s market place. Take that, Cassandra.

While Citus is available as an open source extension, the company that developed it also offers a commercial version with full support. This is a similar model that EnterpriseDB followed with PostgreSQL itself. Citus provides a great option for shops working with Postgres for development and them implementing Citus for extra scalability before going live.

It also lets companies take advantage of their in-house talent’s database skills without spending on training in the latest NoSQL database options. These bonuses are arguably behind the still growing popularity of PostgreSQL.  Elijah Zupancic‏, the Director of Solutions Engineering for Joyent comments on some of the other core reasons.

“From a developer perspective, it is a pleasure to use. The documentation is wonderful, the data types reflect the types developers work with, and there is little surprising.”

A Source Code Search Engine makes Programming more Efficient

No matter your experience level as a software engineer, being able to quickly find code examples helps make your job a bit easier. Most developers know how to write a complex Google search query, as well as being able to navigate GitHub. Nonetheless, having a dedicated source code search engine offers the potential to become more efficient at writing software.

A nascent software developer feels the same way, and is working on a search engine dedicated to finding those valuable code snippets that inspire a solution to a pressing problem. This approach also offers the potential to make learning new languages an easier process. Let’s take a closer look at his efforts.

Learning New Programming and discovering New Functionality

After being exposed to software engineering as part of his college education, Canadian developer, Anthony Nguyen felt there had to be a better way to find relevant code examples. Sure, a Google search helps somewhat, but what about a dedicated search engine specifically for source code? Nguyen began work on SyntaxDB, a tool he hopes to someday be an essential part of any developer’s toolbox.

Michael Byrne first reported on Nguyen’s efforts earlier this year at Motherboard on Vice.com. If Nguyen makes SyntaxDB a success, it becomes another key to making the modern software development team work more efficiently. Interested developers are able to use this emerging resource today.

Byrne notes the tool’s utility for seeing how a common code pattern or piece of functionality gets written in an unfamiliar language. Considering the rapid rate of change in the software development world, new languages and functional libraries get introduced regularly. Having SyntaxDB at the ready helps to speed up the learning process for any programmer.

The Developer Community helping SyntaxDB build its Content

One current weakness noted by Byrne involves SyntaxDB’s relative lack of reference documentation. At the time of his article, it appeared Nguyen himself produced a lot of the internal content returned in the search results.

A robust community of developers willing to help add material to the SyntaxDB database has come to the rescue; potentially increasing the amount of content referenced by the search engine. It currently provides references to many popular languages, including Java, C, C++, C#, Ruby, Go, Swift, Python, and JavaScript.

Adding extensions to allow SyntaxDB to work within the most popular IDE’s is another way Nguyen needs support. He built one for Visual Studio Code and other contributor wrote one for Atom. Nguyen hopes to eventually integrate SyntaxDB into every major IDE and source code editor – a worthy goal, indeed.

Nguyen also wants input from other developers on how to refine the search engine’s interface. He also encourages developers to submit any corrections to the tool’s current source code examples. His current major project with SyntaxDB involves building an interface to easily allow content contributions from other software engineers.

With a goal of becoming the fastest programming reference in the world, Anthony Nguyen gives hope to developers struggling to learn a new programming language or simply how to do something new. Take some time to use SyntaxDB and offer feedback and even add some content of your own.
