OGB Appreciation Day : Support of Hybrid

This is my blog post as part of the Oracle Ground Breakers Appreciation Day (more about this with oracle-base) isn’t about a specific product or feature but an approach or possibly two approaches that exist with many of the PaaS services available from Oracle.

One of the key things that many of Oracle’s products such as Integration Cloud, API Platform and the foundation of Functions (Fn) and Containers is the recognition that many organisations are not so fortunate to be cloud-born, or even working with a cloud-native model for IT. For those organisations who would rather have across location unifying approach, Oracle cloud is not a closed capability like AWS, whilst products like Integration Cloud are at their best on Oracle Cloud Infrastructure, they can be executed in your data centre, or even another cloud.

Whilst the teams I work with experiment and build our service offerings ‘on Oracle’, when we engage with customers to help them with their specific problem spaces, we are more often than not operating in a multi-cloud or on-premises hybrid model.

This hybrid story is helped with a renewed vigour for open source both contributing to but also leading the development of open source. In addition to providing free tiers to some of their stack such as Functions, IaaS and Database (here). Many do forget the Oracle JVM is free as long as you keep up to date, you have got a small footprint Oracle database for free (XE), MySQL is part of the Oracle family. Then many of the modern development technologies are true to the core open-source, Blockchain, Container Engine meaning that the solutions on these layers are portable, can be run on-prem. Yes, Oracle adds value by wrapping these cores with tooling and features that make easier rather than diverging with proprietary Ingress controllers for example.

The irony is that organisations that tend to be associated with a low cost or being faithful to open source goals actually can end up locking you in and appear to be moving away from the original open-source ideals. Consider RedHat, the champion for a lot of open source-based enablement have removed Kubernetes from the official RedHat downloads for their Linux in-favour of a single node license of OpenShift, to get Kubernetes of RHEL you have to go outside of the normal binary source channels (other challenges are documented here).

Could RedHat’s absolute commitment to OpenShift put them into difficult waters?

As a middleware (to use a fading term) or technical architect, I preferred not to get too involved in the detailed OS layer considerations when it can be helped (my Infrastructure Architect colleagues will always know more about NICs, port bonding, kernel versions etc etc than I ever will) and why I prefer to work with PaaS over IaaS.

But there is an undeniable trend where having a greater understanding of the OS is necessary, this is because we’re seeing PaaS expanding to cover code abstracted solutions such as Oracle’s Integration Cloud, Mulesoft, Dell’s Boomi etc. down to every things as code in the form of Terraform, Kubernetes, Docker and of course  microservices.

So what does this have to do with OpenShift?  Well to apply those heady aspirations we’ve had with middleware of “I can build my solution and run it on my platform anywhere” means in the world of microservices I need to find a common denominator on which I can be portable.  This comes in the form of Kubernetes and Docker and we’ll probably see service meshs in due course (Istio, Linkerd etc). Docker obviously brings the need to understand the OS albeit not at the level of bonding network connections, but still a good level of OS knowledge to do things properly. Over the last couple of years there has been a fair bit of work to achieve this with the inertia of Cloud Native Computing Foundation (CNCF), Open Container Initiative (OCI).

Oracle IT Strategies and logging

So I have an objective to get myself certified as an Oracle Technical Architect. Although the training is only open to Oracle and Partners, the exam is open to all.  As you may have guessed from my blog posts I use a lot of Oracle technology. However the Technical Architect examination is based  largely on Oracle’s IT Strategies library, and usually referred to as ITSO. Before non-Oracle users switch off, the ITSO is actually built around presenting solid good solution agnostic practises, and only once that is laid out does the material overlay Oracle products. So at least 75% percent of the material applies regardless of the vendor (yes cynics will say the practises will naturally lead you to products – but hey someone has to be bad guy).  This actually makes it a worthwhile accreditation – as far as any accreditation can go (no I’ve not done a detailed comparison against Open Group’s Certified Architect – very expensive or the BCS accreditation – bound to BCS membership). TOGAF gives your framework, processes, means to communicate, and the ITSO does well at explaining the technical considerations and could be mapped onto the TOGAF Technical Reference Model (TRM) and Standards Information Base (SIB).

The point, I wanted to get across was in the ITSO is an element on Management and Monitoring (E16583-03 if you want the document reference on the Oracle Technology Network). It makes a lot of really good points about monitoring challenges such as bottom up approach where people monitor the parts of the full capability that they’re responsible for, rather than developing monitoring from a business perspective. The rationale for adopting the business based approach is explained (this is not to say you don’t go  into the technical measures & monitors of looking at your infrastructure, databases, services etc. But from the business approach you will capture the information to understand reporting from a user perspective which is how you’ll here about issues.  Through your detailed monitoring decomposition to get the right specific data points you can then look at correlation of monitoring data for root cause analysis, but also see and .

What the I think the document misses, or at least underemphasises is the ever increasing importance of the monitoring and logging of what is happening as systems and environments become ever more elastic and self managing, and have as IBM call it  autonomics. or self healing, self scaling characteristics. So consider trying to diagnose a problem when a user complains of intermittent performance issues, but you have Kubernetes or another tool scaling up your environment for a period and then back down.  Only through measuring from a business context will you able to understand when the user might perceive performance as an issue. Then with  excellent logging and audit data as to what components are doing at all levels – so services maybe behaving perfectly but your scaling mechanisms are scaling back too soon.

This leads to another consideration, for those organisations that absolutely committed to idea of self healing and proving in resilience production, as the famous Netflix Chaos Monkey does. You need to be able to correlate the monkey’s activities to what is happening in your environment. Has the monkey uncovered an issue that manifests in a manner you hadn’t expected and as a result your user see intermittent issues.

This all leads me to a rather good presentation from Jimmi Dyson at RedHat who showed the simple value of ensuring you can get semantic meaning from logging. As that means you and slice and dice the information to get understanding of what is happening and lead to root cause. In Oracle land Oracle Enterprise Manage (OEM) is ensuring the semantic understanding when it come to known products.

I’ve meandered a bit, so key points  consider ITSO or any other vendor equivalent for sources of good practise. Monitor and measure from a business perspective, but still ensure your collecting detailed semantically meaningful metrics.
