Agile making inroads in Government Software Development

Nearing its second decade of use, Agile is finally seeing wide adoption in software development at government agencies. Doug Robinson, the executive director of the National Association of State Chief Information Officers (NASCIO) in the United States reported that 81 percent of state CIOs plan on increasing the usage of Agile and other iterative development methodologies at their shops. News about this Agile implementation growth appeared this week at CRN.

“We’re seeing a lot of excitement in the CIO world to be able to deliver projects on time and within budget using some type of agile methodology,” said Robinson. As government entities tend to be slow to embrace new technology methodologies, this growth in adoption is another obvious sign of the continued maturity of Agile.

Small Teams write more Secure Code

Teams with a small number of developers produce more secure applications compared to groups with more than 20 employees. That is one of the main conclusions from the recently released 2017 CRASH Report, published by CAST Software. As applications grow in size and complexity, they simply become too difficult to manage.

A chief scientist at CAST Software, Bill Curtis, commented on the survey’s findings. “Applications have gotten so big and complex that no single team can understand it all. It might have five or six languages, multiple databases, CRM systems, and you can’t understand all the interactions. That leaves teams making assumptions that in many cases are wrong,” said Curtis.

Shops wanting to write more secure code need to invest in the relevant training for their developers, while giving them the tools for performing both static and dynamic testing. Additionally, involving a third-party team in the final vetting of an application’s security offers a valuable second opinion before the code is deployed to production.

Microsoft switches to Git for Windows Code Source Control

Considering Microsoft’s investment in its own source control systems, it comes as somewhat of a surprise that the tech giant is migrating all the source code for its Windows operating system to the popular open source tool, Git. News about this move appeared this week in Ars Technica.

The reasoning behind this shift lies within Microsoft’s OneCore project which is aimed at simplifying the Windows codebase. Their previous source control solution for Windows, SourceDepot, was straining to handle the massive amount of source code involved, which includes 3.5 million files.

Redmond chose Git because of developer familiarity as well as its open source nature. The basic Git application needed to be updated to seamlessly handle the Windows source code. Microsoft created a fork in the Git code for this purpose and is talking with the other industry giants who use the app – Google and Facebook – about combining their efforts in the future.

The NoSQL Capabilities of PostgreSQL

Many businesses of all sizes leverage PostgreSQL as an open source option to Oracle and other relational databases. Significant cost savings while maintaining a similar level of performance remains a preeminent reason for this switch. A robust community and the availability of commercial-grade support make Postgres worthy of consideration for your traditional database needs. 

With NoSQL gaining popularity all over the technology world, you may wonder how PostgreSQL supports this new database paradigm. Let’s take a look at what functionality exists today in the database with a quick towards the future as well.

Postgres NoSQL for the Enterprise

We’ve talked about EnterpriseDB’s commercial level version of PostgreSQL previously on the blog. The company also offers a Postgres version with support for document databases and key-value stores – two of the most common NoSQL database types. Known as Postgres NoSQL for the Enterprise, this is something worthy of closer attention at companies looking for an open source mix of relational and NoSQL databases.

This Postgres database solution combines the speed and flexibility of NoSQL with the traditional SQL database functionality required for enterprise use – most notably the support for ACID (atomic, consistent, isolated, and durable) transactions. Database instances also easily integrate into the existing business data infrastructure, no matter the platform. In short, it provides the best of both worlds – relational and NoSQL.

ACID transactions are vital for business organizations that depend on the real-time validity of the relationships within its data. Many current NoSQL databases don’t offer this feature, instead following the BASE paradigm which emphasizes speed and availability over the consistency of the data. Postgres NoSQL lets companies combine unstructured and structured data; mixing the performance of NoSQL with the more formalized governance of traditional SQL.

Postgres NoSQL supports many industry standards for programmatic access and data exchange. These include Ruby, Python, and JavaScript for the former, and the JSON and XML formats in the latter case. The superior performance of PostgreSQL combined with the seamless scalability typical of a NoSQL database solution make EnterpriseDB’s combination of Postgres and NoSQL a valid option for any business desiring a flexible database infrastructure.

The Future of PostgreSQL and NoSQL

In a previous article looking at new features of PostgreSQL 10, we noted the relative lack of NoSQL functionality in this newest version of Postgres, slated for release later this year. The new XMLTABLE feature supports the direct querying of data stored in XML documents. Other performance improvements in version 10 bring the speed of the relational database closer to its other NoSQL brethren.

One recent enhancement in Amazon Web Services deserves mention for companies using a mixture of relational and NoSQL databases. The AWS database migration service now includes NoSQL databases, with MongoDB (as a source) and Amazon’s own DynamoDB (as a target) being the first two to be supported. This means companies with a PostgreSQL instance on AWS are able to stream data from Postgres to a DynamoDB instance.

Companies with an investment in PostgreSQL need to explore EnterpriseDB’s NoSQL option to see if any of its features make sense for adding non-traditional database formats to the corporate data infrastructure.

News from the World of Software Development – April 2017

Here is another edition of our monthly news digest at the Betica Blog. We search for interesting and relevant stories to provide insights to your daily application engineering activities. Last month’s digest is available at this link, if you are interested in checking it out.

With spring in full force in the Northern Hemisphere, hopefully these stories inspire your own software development efforts.

The “Internet of Trains” improving the Efficiency of Railroads

The German company, Siemens, plans to open a software development center in Atlanta with the goal of making railroading more efficient. Called the Data Analytics and Applications Center, the company’s efforts are dubbed with the “Internet of Trains” moniker. News about Siemens’ Atlanta investment was reported on in the Atlanta Business Chronicle.

Reducing downtime while increasing the mileage for each train requires an increased investment in digital technology with the hopes of modernizing railway infrastructure as well as the trains and boxcars themselves. Siemens is known all over the world for their power transmission and signaling and control technology used in the rail industry. Their Internet of Trains solution also focuses on data analytics and predictive software.

The company’s Director of Mobility Delivery Services Gerhard Kress commented on the goals of the project. “We are heading towards next-generation maintenance. It is all about increasing up-time and avoiding unplanned downtime. If we predict incidents early enough we, and our customers, can react accordingly,” said Kress.

Siemens’ work is another example of how data analytics and Web-enabled devices are ushering in an era of innovation in many different industries.

The VA hoping to outsource Modernization of its COBOL Systems

The venerable COBOL language surprisingly still lurks in many legacy systems in the financial industry and government agencies. The United States Department of Veterans Affairs hopes to finally enter the 21st Century when it comes to its technology infrastructure, and is looking to outsource the reengineering of their application inventory. News about the VA’s planned migration was published earlier in April at FedScoop.

Acting VA CIO Rob Thomas commented on the reasons behind his department’s move away from internal application development. “We’re going full into commercial — we’re going to be doing software-as-a-service, we’re going to be doing platform-as-a-service, infrastructure-as-a-service. We’re getting out of the software development business — it’s not a core competency. I see a future for us where we go digital platform both on the benefits side and the health side,” Thomas explained.

A business opportunity lurks for software development shops and SaaS providers hoping to gain customers from the government sector. A measure of COBOL knowledge would also help these companies when reverse engineering existing systems.

Incorporate Design Thinking for Better Software Architecture

This week, Forbes published another article by Scott Stiner, CEO of UM Technologies discussing how to incorporate design thinking into the software architecture process. We covered Stiner’s approach to Agile software development in last month’s news digest.

Stiner feels design thinking helps quickly create solutions to solve problems while building a superior user experience. “The Design Thinking process also creates a stronger relationship with the client, considering developers will work closely with the client to understand that client’s core customers. The advantages are many in this regard, and they help speed up the overall development process,” said Stiner.

The entire article is filled with useful insights to help your team build better applications that make your customers happy – and satisfied clients lead to more business opportunities.
