In serverless applications, functions are small and need to execute in less amount of time in a stateless environment. Logging then becomes a challenge for DevOps to do Root Cause Analysis (RCA) or get insights about the behavior of their applications. One logging approach is to add code to your functions to send logs to an external API, which can be a […]
If you work with Cloud Functions, you know that building serverless applications mainly happens by creating actions–small pieces of code that each do one thing well. You can of course sequence actions together or create event-driven workflows. Through our work with customers, we have realized that some scenarios (for example, image processing, file processing, data pipelines) require more time […]
In a serverless application platform, functions as a service (Faas) run opaquely for the most part. In general terms, when a serverless function is invoked, the platform accepts the request and provisions resources before it executes the function. Let’s refer to the duration between accepting the request and the start of the function execution as the […]
Recently, I introduced you to a new tutorial for a database-driven Slackbot. Today, I am going to discuss security details, how the IBM Watson Conversation service is accessing a Db2 Warehouse service from within a dialog. It uses a serverless setup with IBM Cloud Functions. All the necessary credentials to execute the code and to access the Db2 database are automatically bound. Hence, the function code and the dialog don't need any account-specific changes and are generic.
Ever wanted to build a Slackbot, a chatbot integrated into Slack, on your own? I am going to show you how easy it is to integrate Slack or Facebook Messenger with the IBM Watson Conversation service. As a bonus, the bot is going to access a Db2 database to store and retrieve data. The code in the tutorial uses a serverless fashion with IBM Cloud Functions.
IBM Cloud Functions is a functions-as-a-service platform that is powered by Apache OpenWhisk. It is a readily extensible serverless platform that supports functions authored in various programing languages including Node.js,Python, Swift, Java, and PHP. A feature of IBM Cloud Functions that has been around for some time but not well documented is support for native binaries: any executable that is binary compatible […]
While coding and drafting “Mobile app with a Serverless Backend”, We came up with an idea to use Swift on the server-side for the iOS app (it’s an interesting use case).So, that it will cater the full stack swift developers out there. The same is true for the Android version of the app as well.
2017 has been a year of transition, especially in the realm of exciting new technologies. We're wrapping up 2017 with your top picks from the year, including announcements, how-to's and innovative use cases, to help you prepare for what's to come in IBM Cloud next year.
