Availability and reliability are rarely at the front of developers minds when delivering new applications on Bluemix. The ease and speed of creating and deploying new features is very seductive.
Successful delivery of cloud applications requires more than a focus on agile development. Operations is also essential to maintaining user satisfaction, access and to scale with growth. Cloud operations is different to traditional approaches to operations.
Having worked with many clients over the last 10-15 years in the data protection space, one of most common questions that I have been asked is "How is Backup difference than Disaster Recovery?" There is usually quite a bit of confusion around the conceptual differences, so let me avail this opportunity to explain the differences between the two and explain how these terms have evolved over time.
As your app gets more users and traffic how do you scale its components to handle the additional load?
This weekend saw a large scale 'ransomware' attack. It affected among other institutions, the National Health Service in the UK. Patient treatment was delayed and new born babies had to stay at hospitals a little longer than they should, because their identity couldn't be registered. This made me wonder if health records stored in blockchain could been used to prevent ransomware attacks.
How do Cloud Foundry, Kubernetes, OpenWhisk differ and which one would you pick for your next project?
This 3-part series of posts helps you understand the in-depth features of Serverless Computing via OpenWhisk. OpenWhisk offers an easy way to chain services where an output of first action acts as an input to the second action and so on in a sequence. This post describes the resource requirements for performing this lab.
Serverless computing and Watson service chaining via OpenWhisk : Part 3 of 3 expose an action or sequence
By now, you should be aware of what OpenWhisk is and leverage OpenWhisk Sequence to chain Watson services. Also, you should have created Swift and NodeJS actions for transforming the JSON to required formats. In this post, you will learn how to expose an action or a sequence (Chain of actions) as a RESTful endpoint via OpenWhisk API Gateway and OpenWhisk CLI.
In Part 1 of this series, you learned the basics of Serverless computing and the building blocks behind OpenWhisk. In this post, you will create Watson Services and add them to an OpenWhisk Sequence on IBM Bluemix. As our post is all about chaining Watson Services using OpenWhisk, in this section you will create three Watson Services
