Rapid Mobile App to API Integration

Wireframes for user interface design are still a good idea when communicating requirements to others, however lately I would rather create them as a HTML5 prototype that is usable across heterogeneous devices with various screen sizes and resolutions. One such tool that I prefer is from Appery.io, which is a browser based jQuery and PhoneGap powered mobile application development studio. Appery.io offers a faster path to publish an application in an App Store because once the HTML5 prototyping, user acceptance testing and usability work is complete, it can also generate the Android apk and IOS binaries without the need to port to Objective C manually. This feature alone is a major time saver, and so is the drag and drop JSON API response test message to UI component designer that creates a wireframe that will also generate the runtime code.

Let’s say you have your APIs ready to consume and you know what data elements need to be displayed to the user. Perhaps some of the APIs are SOAP/XML and others are REST/JSON and they are secured with different authentication protocols.

To simplify the user interface design process, let’s agree to transform the SOAP services to REST APIs using an API Gateway to also transform the XML to/from JSON. Then configure the API gateway to mediate the authentication on the client app side from OpenID & OAuth to the various different security protocols required for the downstream APIs being consumed. This avoids the need to require different credentials for each API in the client application code, and improves the security of the system by limiting the connections to the APIs to only the API gateways, greatly reducing the attack vector and lowering the risk of system outages and malformed requests that reach the application/data tier.

Now that security and API transformation is in place, we are ready to begin mobile application client development. First the developer will request an application ID and secret from the API developer portal that is linked to the API gateway cluster’s policy decision point. The app id will be used in an Authorization header by the client app in order to begin the OAuth process to authenticate the user and receive a token, thus avoiding the need to send user credentials with each API call and simplifying the authorization process to restrict which API operations can be used based on the “scope” of the token. The user will only be prompted to authenticate when the token has expired and there is no valid refresh token.

When creating the HTML5 client application using Appery.io the process is to first configure a GET API request for an authorization code from the OAuth server then to submit a POST request for the access and refresh tokens. These values will be parsed and stored into variables that can later be accessed using JavaScript to insert the tokens into the Authorization header for each subsequent API call that the application will make.

Next add the APIs that will be used by the application to retrieve the data requested by the user of the mobile app and save the response of each test call. After placing the fields on the canvas that will display the data returned, the data tab of the UI designer is used to visually wire (drag and link) the field in the JSON response payload to the field on the user interface that will display that string of text. Once all of the input and output fields are mapped, test the app to view the HTML5 version in your browser using the QR code that links to the app sandbox URL. In under an hour you’ve now got alpha wireframes and a secured prototype that is ready to share.

Experiment with portrait vs landscape given that not all users share the same perspective and adjust for inconsistencies across device type. Begin the UAT process and iterate iterate iterate.

Appery.io and SOA Software are partnering because SOA makes it easy to configure the API security properly and the SOA policy manager and API gateway make it easy to debug the API requests, and the Community Manager API portal is a turnkey solution that will generate client application IDs that are linked to SLA Quality of Service policies with reports to track how the mobile apps are consuming the various APIs.

DevOps is often described as a combination of technology and culture. Without both, DevOps isn't complete. However, applying the culture to outdated technology is a recipe for disaster; as response times grow and connections between teams are delayed by technology, the culture will die. A Nutanix Enterprise Cloud has many benefits that provide the needed base for a true DevOps paradigm. In his Day 3 Keynote at 20th Cloud Expo, Chris Brown, a Solutions Marketing Manager at Nutanix, will explore t...

There are two main reasons for infrastructure automation. First, system administrators, IT professionals and DevOps engineers need to automate as many routine tasks as possible. That’s why we build tools at Stackify to help developers automate processes like application performance management, error monitoring, and log management; automation means you have more time for mission-critical tasks. Second, automation makes the management of complex, diverse environments possible and allows rapid scal...
This talk centers around how to automate best practices in a multi-/hybrid-cloud world based on our work with customers like GE, Discovery Communications and Fannie Mae. Today’s enterprises are reaping the benefits of cloud computing, but also discovering many risks and challenges. In the age of DevOps and the decentralization of IT, it’s easy to over-provision resources, forget that instances are running, or unintentionally expose vulnerabilities.
It has never been a better time to be a developer! Thanks to cloud computing, deploying our applications is much easier than it used to be. How we deploy our apps continues to evolve thanks to cloud hosting, Platform-as-a-Service (PaaS), and now Function-as-a-Service. FaaS is the concept of serverless computing via serverless architectures. Software developers can leverage this to deploy an individual "function", action, or piece of business logic. They are expected to start within milliseconds...
We all know that end users experience the internet primarily with mobile devices. From an app development perspective, we know that successfully responding to the needs of mobile customers depends on rapid DevOps – failing fast, in short, until the right solution evolves in your customers' relationship to your business. Whether you’re decomposing an SOA monolith, or developing a new application cloud natively, it’s not a question of using microservices - not doing so will be a path to eventual ...
One of the biggest challenges with adopting a DevOps mentality is: new applications are easily adapted to cloud-native, microservice-based, or containerized architectures - they can be built for them - but old applications need complex refactoring. On the other hand, these new technologies can require relearning or adapting new, oftentimes more complex, methodologies and tools to be ready for production. In his general session at @DevOpsSummit at 20th Cloud Expo, Chris Brown, Solutions Marketi...

The first step to solving a problem is recognizing that it actually exists. And whether you've realized it or not, cloud services are a problem for your IT department. Even if you feel like you have a solid grasp of cloud technology and the nuances of making a cloud purchase, business leaders don't share the same confidence. Nearly 80% feel that IT lacks the skills necessary to help with cloud purchases-and they're looking to cloud brokers for help instead. It's time to admit we have a cloud s...
According to a recent Gartner study, by 2020, it will be unlikelythat any enterprise will have a “no cloud” policy, and hybrid will be the most common use of the cloud. While the benefits of leveraging public cloud infrastructures are well understood, the desire to keep critical workloads and data on-premise in the private data center still remains. For enterprises, the hybrid cloud provides a best of both worlds solution. However, the leading factor that determines the preference to the hybrid ...
In this modern world of IT, you've probably got some new colleagues in your life-namely, the cloud and SaaS providers who now hold your infrastructure in their hands. These business relationships-yes, they're technology-based, but cloud and SaaS are business models-will become as important to your IT team and your company as the hardware and software you used to install. Once you've adopted SaaS, or inherited SaaS, it's on you to avoid price hikes, licensing issues and app or provider sprawl....
