You probably heard that Oracle Autonomous Database (ADB) leverages machine learning to automate with traditional infrastructure related database administration tasks such as security, backups and patching.
Even in a day and age where event-based and real-time data exchange is prevalent and growing, the truth is there are still massive amounts of data exchanged using file transfer mechanisms. Oracle has always played in this realm, but with limited success. The Oracle Managed File Transfer (MFT) application is pretty good, but nothing to write home about… or write a blog about! 😀
One reason is because moving files around and using FTP servers is not very glamorous. Another reason is because the Oracle MFT management dashboard is pretty limited. It is able to monitor various aspects of a file transfer, report success or failure and allow you to resend files. But it has no business context or the ability to understand how a file might be part of a larger business process.
Last weekend, I was at the Code Network Winter Hackathon event in Brisbane – https://codenetwork.co/winter-hackathon-2018/. I was there as a sponsor, workshop presenter, mentor and just a general supporter. As such there was some down-time between different activities. So, what a great time to sit down and work on something that I have no idea about (technically) – #Blockchain and Hyperledger. So, as a normal person does – I went searching for relevant content to help. Here’s a couple of the searches that I did.
Unfortunately, through many different searches and reading lots of things it became apparent that I didn’t know much and there was lots to learn. There seemed to a massive amount information that looked great. There was content that talked about what a Blockchain is. There was content that talked about the business use cases and examples of why you use a Blockchain technology. There was code that built a Blockchain. I found plenty smart contract examples on github. I learnt more about what I needed to know but it didn’t get me to the place that I wanted to be.
So – how do I develop and play with a Smart Contract?
Oracle is adding a secret recipe to all their Cloud Services with a nice touch of Machine Learning. This makes it possible to have the new series of “Autonomous” Cloud Services that are self-driving, self-healing and self-securing. Stay tuned, because we are going to keep listening a lot about them.
In this blog I am going to show you how to provision an Autonomous API Platform environment and then provision and register an API Gateway, running on a separate Oracle Linux VM on IaaS.
This is a graphical view of what I will be doing in this blog:
We have covered multiple blogs on how to use Terraform to help automate the provisioning of environments and treat your Infrastructure as Code. Until now, for PaaS stacks, we have used Terraform together with Oracle PaaS Service Manager (PSM) CLI. This gives us great flexibility to script our own tailored PaaS stacks the way we want them. However, with flexibility comes responsibility, and in this case, if we choose to use PSM CLI, it’s up to us to script the whole provisioning/decommission of components that make up the stack. As well as what to do if we encounter an error half-way through, so that we leave things consistently.
A simpler way to provision PaaS stacks is by making use of Oracle Cloud Stack, that treats all components of the stack as a single unit, where all sub-components are provisioned/decommissioned transparently for us. For example, Oracle Integration Cloud (OIC) stack, is made of Oracle DB Cloud Service (DBCS), Integration Cloud Service (ICS), Process Cloud Service (PCS), Visual Builder Cloud Service (VBCS), IaaS, storage, network, etc. If we use Oracle Cloud Stack to provision an environment, we only have to pass a YAML template with the configuration of the whole stack and then, Cloud Stack handles the rest. Pretty awesome huh?
Similarly, as we have done in the past, we are going to use a “Build Server”. This will be used as a platform to help us provision our PaaS stacks. When provisioning this “Build Server”, I will add all the tooling it requires as part of its bootstrap process. For this, I am using Vagrant + Terraform, so that I can also treat my “Build Server” as “infrastructure as code” and I can easily get rid of it, after I built my target PaaS stack.
This is a graphical view of what I will be doing in this blog to provision an OIC stack via Cloud Stack:
In this blog, I am going to show you how quickly you can use data in an existing Excel spreadsheet with multiple tabs and use it to auto-generate API-based microservices using Oracle Visual Builder. Then, we are going to consume our own generated APIs via a rich set of HTML5 components.
For demonstration purposes, I am going to upload an Excel spreadsheet that contains 3 tabs (Order, Buyers and Products). This is a simple way to play with master/detail records. Feel free to use the same spreadsheet as an initial demo vehicle to auto-generate REST APIs and build Web Applications.
