Teaching How to get Microservices to Consume Oracle Autonomous Transaction Processing Database (ATP)

A few days ago, we published an article that shows how to provision and connect to Oracle Autonomous Transaction Processing Database (ATP). Based on this, we got multiple requests to also demonstrate how to extend the connection to the Autonomous DB, not only from SQL Developer, but also from polyglot microservices.

In this blog, we are going to take a step forward and create a simple “Hello World” NodeJS application that exposes some REST APIs that push and pull data using an Oracle Autonomous DB. The idea is to give you all knowledge required, to be start building your own microservices, consuming data from Autonomous DB.

Teaching How to get started with Autonomous Database for OLTP

We all know that data is massively valuable to businesses, whether it is to support daily business transactional activities (Online Transaction Processing – OLTP), or to help business with planning, problem solving and decision making (Online Analytical Processing – OLAP). Either way, businesses heavily rely on both ways to support their most important strategies and activities.

Until recently, companies had to heavily invest in provisioning, securing, patching and driving either way of Online Data processing mechanisms. In most cases, even with Cloud adoption, companies still had to rely on their own skills to make sure that their databases were properly patched, secured, tuned and managed.

However, today there is another option with the recent announcements that Oracle have made around Autonomous Databases for both OLAP and OLTP data processing. What this means, is that Oracle has taken automation to a totally new level with the assistance of Machine Learning. The idea is that the DB itself is self-sufficient with a full set of automated activities that range from patching, securing, optimising, etc. This will reduce not only the effort to run data workloads, but removing completely human errors, creating the opportunity to not only keep the lights on, but to focus on crucial business activities around innovation and differentiation.

Teaching How to Provision Oracle Autonomous API Platform and API Gateway

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:

Teaching How to Provision Oracle Integration Cloud (OIC) with Cloud Stack and Terraform

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:

Teaching How to Get Started with Oracle Autonomous Data Warehouse Cloud Service

Data Warehouses have been around for a long time and they bring multiple benefits, but these also come at a cost. Some of the associated challenges that are easily identified when talking about traditional Data Warehouses include:

  • Complexity and Expensive
  • Inability to manage data and user growth
  • Hard to deploy and maintain

Oracle Autonomous Data Warehouse aims at easing these challenges with the ability to:

  • Provision a data warehouse in as little as 15 seconds.
  • Full automation of management of the Data Warehouse
  • Instant scaling with zero-downtime
  • Automated Tuning
  • Migration tools, e.g. Redshift

In this blog, let’s show can easily we can provision a new Oracle Autonomous Data Warehouse, load data into it and run some data visualization on top.

Learn how Containers and Kubernetes fit together – Live Workshop

Need to understand how Containers, Kubernetes and the Cloud-Native Landscape fit together?

Organisations are excited about the cloud-native approach as it helps provide parity between development and production environments, adoption of the DevOps framework, and enables software developers to build great products faster.

This new paradigm in application delivery has brought with it much new jargon and tooling – “Containers”, “Docker”, “Kubernetes”, “Container Orchestration”, and “Microservices” are fast becoming the new norm.

Save time and get up to speed on the business value and technical know-how of these contemporary, cloud-native concepts and tools, including:

  • CNCF Landscape
  • Containers
  • Docker
  • Kubernetes
  • Microservices

Teaching How to Get started with Kubernetes deploying a Hello World App

In a previous blog, I explained how to provision a new Kubernetes environment locally on physical or virtual machines, as well as remotely in the Oracle Public Cloud. In this workshop, I am going to show how to get started by deploying and running a Hello World NodeJS application into it.

There are a few moving parts involved in this exercise:

  • Using an Ubuntu Vagrant box, I’ll ask you to git clone a “Hello World NodeJS App”. It will come with its Dockerfile to be easily imaged/containerised.
  • Then, you will Docker build your app and push the image into Docker Hub.
  • Finally, I’ll ask you to go into your Kubernetes cluster, git clone a repo with a sample Pod definition and run it on your Kubernetes cluster.
