In today’s environment where systems run in the cloud and so much business and personal activity occurs online, passwords are not strong enough by themselves to protect applications. Scandals about password breaches seem to happen on a regular basis. It’s easy to find many case studies where passwords have been compromised as a result of malware, email scams and other techniques. The key point is that no matter how strong our passwords, no matter how much we educate our users, there will be situations where people are caught off guard and click on the wrong link, look at the wrong email or open the wrong document. Once this happens, our passwords can be compromised.
The May 2017 update for ACCS (17.2.3) brought a cool new feature to ACCS, zero-downtime updates. While previously, there was support for performing a rolling restart of an application instance, where each instance would be brought down and updated in turn, this only enabled zero-downtime updates if you had an application running two or more instances, and your application could satisfy performance requirements with one fewer node. While any production system should be able to satisfy these requirements, many of the utility systems I ran were on a single node, and I had to send out an email blast to avoid being disruptive when I wanted to push a quick code fix.

Throughout my development experience, I feel that I have had several major bursts-of-learning, due to problems which have made me re-evaluate how I approach architecting and developing a solution. I feel these ultimately make me better as a programmer, or at the very least, more versatile. I am sure some of these bouts of learning and understanding are near universal, experienced by most developers, such as understanding parallelisation, but others are somewhat more specialised, such as when I first started writing games, where having to take 60+ snapshots of a continuously evolving environment every second completely changed how I thought about performance and accuracy. Developing Cloud-Native applications (and indeed micro-service based applications, which share very similar principles) feels as though it is one of these moments in my development experience, and I feel it might be interesting to reflect upon that learning process.
I see the problem statement for Cloud-Native applications as something akin to: ‘you have no idea how many instances of your application will be running, you have no idea where they will be in relation to one another and you have no idea which one will be hit for any particular call’. That is a lot of unknowns to account for in your code, and forces you to think very carefully about how you architect and develop your applications.
We were looking into some of the VM images that we have. Some of them were very useful but we were wanting to host them in the cloud for the upcoming workshops.
Ravello is a cloud service that allow you to import and manage your VMs or stacks of VMs on public cloud. The interesting part of this is that the service can use our cloud infrastructure or a third party cloud. Ravello manages the costs but also adds simple capability to manage your VMs better.
Here’s a quick guide to putting VMs (I did a VirtualBox image but it can be any type) in the Oracle Cloud with Ravello.
Oracle is moving fast in the IaaS world.
I’ve been using the Oracle Cloud IaaS service for quite some time now. I spin up various forms of OEL or Ubuntu and deploy applications on top.
But did you know there are many ways to spin up common platforms on top of IaaS with no installation required? Bitnami is one option, but there is a “hidden” menu item that few people know about and I want to share that with you now.
