With only three days remaining for my 30-day trial, I will finally close these series by discussing my experiences dealing with various levels of support from Oracle. Having used the Oracle Cloud (OCI) both in my day job and as a technology evangelist, I have had the opportunity to engage Oracle support at various levels: sales, customer and technical.
Oracle Function was announced late last year (2018), with limited availability to select Oracle Cloud customers. The platform is built on Fn and is Oracle's solution for developers wanting to deploy services using a Serverless Framework.
As succinctly explained by Kaslin Fields, a Fn function is a small embodiment of code that listens and speaks to HTTP streams. Ideally, each Fn function serves one, and only one purpose. It can be implemented in wide variety of programming languages and they are listed here (see the list of runtime options available).
In case you missed it (which is almost impossible), the Oracle Autonomous Database (AutonomousDB) is Oracle's hottest offering on the Oracle Cloud and it now comes fitted with what is arguably the best feature of the Oracle Database: Oracle Application Express (APEX). I have a few more days to go with this trial, so why not take one out for a spin?
To everyone following my 30 Days on the Oracle Cloud experience, I apologise that I was not able to keep up with the series previously, due to work commitments. I have enrolled in yet another trial, so I am hoping to continue where I left off and share my thirty day adventure with an Oracle Cloud trial. I'm on Day 14 now, and for this post, I'll examine an important issue that many of us face, even in our personal life - moving houses!
I was glad to be back in Seattle to attend the 2019 edition of ODTUG's famed Kscope conference. This is the second time the event is held this close to home (read my previous recount of the same conference five years ago)! And like every Kscope before, the conference always provides unique experiences, bountiful knowledge and new people to meet! Here's a quick summary and highlights of my week.
Since Oracle Application Express (APEX) version 18.1, application developers are able to easily integrate OAuth2-based authentication using many popular identity providers including Google, Facebook and Microsoft. Morten Braten, Anton Nielsen and I have previously written on this subject.
Starting May 2019, Microsoft is changing how developers manage their OAuth2 application registrations.
One of my fondest memories of my previous job was working with VMware virtualization products. With VMware Workstation, system administrators had the ability to "move" a virtual machine (VM) from a local workstation to vSphere. It was no surprise then that I was very exited (and itching to play) when VirtualBox 6.0 was released with a new feature: support for exporting a VM to Oracle Cloud Infrastructure (OCI)!
It took a little longer than I had hoped to publish the next article in this series about my experience with a 30-day Oracle Cloud trial. I had a created compute instance in the same compartment and that messed up my estimates. That's just one piece of the puzzle.
After running my Oracle Application Express (APEX) instance (see the previous article on what it takes) for more than a day, I think I have enough to take a first measure of costs and fact check the prices listed by Oracle!
Remember this ad?
IBM BladeCenters were revolutionary at its time. System Administrators would know that one of the largest expense when building out a server infrastructure is real estate costs. Shrinking racks of servers and consolidating into blade servers meant you could put more hardware in less space. However, they were expensive and had their fair share of skeptics. Adopting a proprietary backbone simply meant you were investing into a brand and hence subject to vendor lock-in.
Then came virtualization. With more powerful CPUs, cheaper RAMs and more cost-effective storage solutions, we are now able to cramp more servers into a single server. Other pieces of traditional server infrastructure, e.g. network and storage, could be "software-defined". The server footprint very much "vanished into thin air"!
I have read many comments on social media and blogs about various experiences using the Oracle Cloud for hosting web applications and databases. There are probably more bad than good accounts, and so I wanted to experience the process myself using a trial subscription.
Typically, a trial account only gets you a US$300 credit to use on the Oracle Cloud. The credits are good 30 days, after that, either your upgrade to a paid plan, or you lose everything. You are also required to provide a valid credit card for verification purposes only. According to the sign up page, users are only billed after choosing to "upgrade" the account.
When Oracle Database 18c Express Edition (18cXE) was released late last year, I was motivated to work on an image for running the newly released, FREE database using Docker. The scripts were based on the official Docker images published by Oracle. With much help from Martin D'Souza, we released the scripts to the community with pointers on how to install and run an Oracle Application Express (APEX) stack.
Late last year, I started binge watching the entire four seasons of The Last Ship. It was one of the rare TV serials that my wife and I shared a common interest in. I think this was mostly because the first season was centered around the ship and its crew's fight against total human annihilation by an infectious disease. For me though, it was also about the military hardware and camaraderie amongst the soldiers.
I have written on two occasions, "Just a Drop of Oracle APEX" and "APEX and the Affordable Cloud!", about how easy it is to get up and running on hosting providers like Linode and DigitalOcean. The approach largely involves Vagrant, and though it is an easy to use tool, it still needed a little bit of DevOps heroism, and sometimes, dealing with API keys may not necessarily be a priority for someone looking for a quick way to setup a consistent and robust Oracle Application Express environment.
Updated November 18, 2018 Added a help utility to populate an Oracle Wallet with root certificates
Oracle Database 18c Express Edition comes with a usable Oracle Wallet. In a previous article, I had described how to:
Someone had asked in the comments, what certificates were necessary for Social Sign-in in Oracle Application Express (APEX) to work. It's something that I think most of us would like to know too, so I did a little more digging and here's what I found for three of the more popular social platforms: Google, Facebook and Microsoft.
