Build and test microservices applications with Azure Dev Spaces

Tue, 07/17/2018 - 06:00

Azure’s service platform’s adoption of Kubernetes and containerschanges how you build, deploy, and manage cloud-native applications, treating containers and services as the targets of your builds, rather than the code that makes up those services.

Kubernetes itself automates much of what had been infrastructure tasks, orchestrating and managing containers. Azure’s AKS tools simplify configuring Kubernetes, but you need to deploy straight into an AKS instance—a hurdle for anyone developing new apps or handling a migration of an existing service. Although AKS itself isn’t expensive, setting up and tearing down orchestration models takes time—time that can better be spent writing and debugging code.

No blank checks: The value of cloud cost governance

Tue, 07/17/2018 - 06:00

How much does you’re public cloud cost month to month? If you don’t know, you’re hardly alone. Most people in IT don’t have a good understand of what a public cloud service costs per month. Most wait to find out what the bill says rather than proactively monitor cloud consumption, much less have cloud cost governance in place.

Even if your financial budgeting model can handle uncertain costs, not knowing what you’re spending has a downside. When you moved to the public cloud, your company put a value driver in place when defining the business cases—and part of that was based on ongoing costs per month.

[ Get started: Azure cloud migration guide. • Tutorial: Get started with Google Cloud. | Keep up with the latest developments in cloud computing with InfoWorld’s Cloud Computing newsletter. ]

If those costs are higher than originally estimated, the value metrics won’t support your goals. Although you can make a case for the cloud’s value around agility and compressing time to market, that will fall on deaf ears among your business leaders if you’re 20 to 30 percent over budget for ongoing cloud costs.

PyTorch review: A deep learning framework built for speed

Mon, 07/16/2018 - 06:00

Deep learning is an important part of the business of Google, Amazon, Microsoft, and Facebook, as well as countless smaller companies. It has been responsible for many of the recent advances in areas such as automatic language translation, image classification, and conversational interfaces.

We haven’t gotten to the point where there is a single dominant deep learning framework. TensorFlow (Google) is very good, but has been hard to learn and use. Also TensorFlow’s dataflow graphs have been difficult to debug, which is why the TensorFlow project has been working on eager execution and the TensorFlow debugger. TensorFlow used to lack a decent high-level API for creating models; now it has three of them, including a bespoke version of Keras.

Understand parameter binding in ASP.Net Web API

Mon, 07/16/2018 - 06:00

ASP.Net Web API is a lightweight framework that can be used for building RESTful HTTP services. When working with controller methods in Web API, you will often need to pass parameters to those methods. A “parameter” here simply refers to the argument to a method, while “parameter binding” refers to the process of setting values to the parameters of the Web API methods.

Note that there are two ways in which Web API can bind parameters: model binding and formatters. Model binding is used to read from the query string, while formatters are used to read from the request body. You can also use type converters to enable Web API to treat a class as a simple type and then bind the parameter from the URI. To do this, you would need to create a custom TypeConverter. You can also create a custom model binder by implementing the IModelBinder interface in your class and then implementing the BindModel method. For more on type converters and model binders, take a look at this Microsoft documentation.

How to align test automation with agile and devops

Thu, 07/12/2018 - 06:00

One key devops best practice is instrumenting a continuous integration/continuousdelivery (CI/CD) pipeline that automates the process of building software, packaging applications, deploying them to target environments, and instrumenting service calls to enable the application. This automation requires scripting individual procedures and orchestrating the steps from code checkin to running application. Once matured, devops teams use the automation to drive process change and strive to do smaller, more frequent deployments that deliver new functionality to users and improve quality.

The key to proactive multicloud cost management

Wed, 07/11/2018 - 06:00

Sebastian Stadil is the CEO and founder of Scalr.

Enterprises are moving to multicloud in droves. Why? The key drivers most often cited by cloud adopters are speed, agility, platform flexibility, and reduced costs—or at least more predictable costs. It’s ironic then that more than half of these companies say that runaway cloud costs are their biggest postmigration pain point.

Docker tutorial: Get started with Docker Hub

Wed, 07/11/2018 - 06:00

The power of Docker images is that they’re lightweight and portable—they can be moved freely between systems. You can easily create a set of standard images, store them in a repository on your network, and share them throughout your organization. Or you could turn to Docker Inc., which has created various mechanisms for sharing Docker container images in public and private.

The most prominent among these is Docker Hub, the company’s public exchange for container images. Many open source projects provide official versions of their Docker images there, making it a convenient starting point for creating new containers by building on existing ones, or just obtaining stock versions of containers to spin up a project quickly. And you get one private Docker Hub repository of your own for free.

Be smart about edge computing and cloud computing

Tue, 07/10/2018 - 06:00

I hear it every day now: “We’re moving beyond cloud computing to edge computing.” Pretty hypey, and not at all logical.

Edge computing is a handy trick. It’s the ability to place processing and data retention at a system that’s closer to the target system it’s collecting data for as well as to provide autonomous processing.

[ What is cloud computing? Everything you need to know now. | Also: InfoWorld’s David Linthicum explains what exactly is edge computing. ]

The architectural advantages are plenty, including not having to transmit all the data to the back-end systems—typical in the cloud—for processing. This reduces latency and can provide better security and reliability as well.

How to develop cross-platform apps more easily with Xamarin.Essentials

Tue, 07/10/2018 - 06:00

The Xamarin acquisition was one of Microsoft’s smartest deals. It quickly gave it access to tools that let developers use familiar tools and technologies to build cross-platform applications. Now built into every version of Visual Studio, and providing the basis for its MacOS Visual Studio release, Xamarin has become a key element of Microsoft’s development tools.

Until recently—even with Xamarin—building cross-platform applications wasn’t easy. For all that the core development tools handle working with iOS and Android from .Net, using it to build apps meant having significant amounts of device-specific code to handle both native UX and deep platform integration. Although you could keep your core code across device-specific projects, building and testing the full application required domain knowledge and specialized skills. The result was code that, although a little cheaper than using native tools for each platform, really wasn’t as cheap to build as it could have been.

GitHub vs. Bitbucket vs. GitLab: An epic battle for developer mindshare

Mon, 07/09/2018 - 06:00

It’s the kind of meta notion that makes undergraduate philosophers say, “Whoa!” Software today is so complicated that we need to write software to help us understand and construct the software we need to write. Code begets code begets more code…

The code repository named Git is everyone’s favorite tool for curating software, but even this neat open source software isn’t enough. Most programmers and the teams to which they belong are now wedded to online versions of Git that add many extra layers of analysis and presentation to make it possible to wade through the vast swamp that is our code.

You can no longer afford to indulge cloud blockers

Fri, 07/06/2018 - 06:00

Cognitive dissonance occurs when beliefs or assumptions are contradicted by new information. People address that tension with one of several defensive maneuvers: Often, they reject or avoid the new information, or they resort to other defensive means of preserving order in their conceptions of reality.

What does this have to do with cloud computing? A lot, these days.

[ What is cloud computing? Everything you need to know now. | Also: InfoWorld helps you identify the right tools for the job: AWS cloud services guide • Microsoft Azure services guide. • Google Cloud Platform services guide. ]

For many IT professionals a decade ago, cloud computing was not secure, overpriced, unreliable, and other otherwise evil. In the early days, they loudly agitated against the cloud notion. Today, those people largely keep their opinions to themselves, but more of them are out there than you know.

MySQL tutorial: Get started with MySQL 8

Thu, 07/05/2018 - 06:00

MySQL remains one of the most common and consistent elements in the modern application programming stack. If you want a database for your app or service, and your needs are fairly generic, MySQL is one of the easy defaults. It’s widely used and well-understood, so you can draw on a wealth of community knowledge and experience when deploying MySQL for your particular application.

The latest major revision, MySQL 8, fixes a number of long-standing issues with MySQL—changes major enough to demand a revision to the left of the decimal point.

How Red Hat has come to dominate Kubernetes

Thu, 07/05/2018 - 06:00

In the old world, the operating system was the center of the computing universe. In today’s modern application age, container platforms fill the space once occupied by the OS. That fact helps to explain why so much cash and code is pouring into Kubernetes.

What it doesn’t explain, however, is why comparatively few companies are investing heavily enough in Kubernetes. Given the central role Kubernetes seems destined to play in shaping enterprise infrastructure, we should see more competition to contribute, given that more code tends to equal more influence in open source. Oddly, only Google and Red Hat seem to be playing to win in Kubernetes, based on contribution counts.

4 essential features of modern low-code development platforms

Wed, 07/04/2018 - 06:00

Malcolm Ross is vice president of product at Appian.

Today’s low-code app development platforms can play an essential role in any business undergoing digital transformation. As needs ebb and flow and new market opportunities present themselves, agile organizations require a way to innovate faster and speed time to market. While traditional development cycles are complex and can take months, modern low-code development platforms simplify the complexity of enterprise software development and enable deployment in weeks or days.

Low-code development platforms are not new. Rapid app development tools, like Visual Basic, PowerBuilder, and, to a lesser extent, Microsoft Access, have been around for decades, giving developers simple, easy-to-use platforms for creating applications quickly and efficiently with minimal or no coding required.
