Istio In Action

book, Istio, K8s, Kubernetes, manning, mesh, mindmap

Christian Posta and Rinor Maloku’s book with Manning, Istio In Action has just been published. I’ve previously said it’s a good book, and that’s not surprising given Christian’s role at solo.io. When the final chapters became available I started to go through it in more detail and built a mind map (As with the recent review of Kubernetes best practices). The map can be seen below.

As you can see the map is very substantial reflecting on the depth and value of the book. For those who look at the maps, may notice there are a couple of chapters not fully mapped. I will update the map to fill those gaps in, but given they focus on monitoring and observability, I was less concerned about those areas given my own writing. The book’s exercises are very much built around using Docker Desktop making it very easy to spin up the examples and exercises. If you want to know about Istio Service Mesh on K8s then I’d recommend it.

Reading through the book, I’ve learned details that I was not entirely aware of, for example the integration of non K8s workloads into the mesh. The tuning of Istio to keep it highly performant with a lot of workloads.

The book can be obtained from:

  • Manning
  • Amazon

And other retailers of course.

Kubernetes Best Practises – Review & Mindmaps

"best practise", book, Istio, Kubernetes, mindmap, review

I’ve had some time to catch up on books I’d like to read, including Kubernetes Best Practises in the last few weeks. While I think I have a fair handle on Kubernetes, the development of my understanding has been a bit ad-hoc as I’ve dug into different areas as I’ve needed to know more. This meant reading a Dummies/Introduction to entry style guide would, to an extent, likely prove to be a frustrating read. Given this, I went for the best practises book because if I don’t understand the practises, then there are gaps in my understanding still, and I can look at more foundation resources.

As it goes, this book was perfect. It quickly covered the basics of the different aspects of Kubernetes helping to give context to the more advanced aspects, and the best practices become almost a formulated summary in each section. The depth of coverage and detail is certainly very comprehensive, explaining the background of CNI (Container Network Interface) to network-level security within Kubernetes.

The book touched upon Service Meshes such as Istio and Linkerd2 but didn’t go into great depth, but again this is probably down to the fact that Service Mesh ideas are still maturing, and you have initiatives like SMI (Service Mesh Interface still in the CNCF’s sandbox).

In terms of best practices, that really stood out for me:

  • Use of Taints and Tolerations for refined control of pod deployment (Allowing affinity to be controlled to optimise resilience, or direct types of pod deployment to nodes with specialist capabilities such as GPU).
  • There are a lot more differences and options then you might realize in terms of ingress controller capabilities, so take time to identify what you may need from an ingress controller.
  • Don’t forget pods can be scaled vertically with the VPA (Vertical Pod Autoscaler)as well as horizontally through the HPA.
  • While using a managed persistence service will make statement storage a lot easier, stateful sets will give you a very portable solution.

As with a lot of technical books I read. As I go through the book I build up a mind map of what I think are the key points. Doing so leaves me with a resource I can use as a quick reference, but creating the mind map helps reinforce the learning. So here is the mind map …

API, book, GraphQL, mindmap

We’ve added a new mindmap to our catalogue here. This covers the core of GraphQL. The catalogue contains both the image and a Word representation. The map is built based on a reading of Learning GraphQL by Eve Porcello  & Alex Banks on O’Reilly.

Building Evolutionary Architectures

architecture, book, evolutionary, mindmap, review, Technology

I have been working my way through Building Evolutionary Architectures by Neal Forward, Rebecca Parsons and Patrick Kua. Three senior and respected members of Thoughtworks (also the home of Martin Fowler). Having read and listened to Neal and Rebecca’s presentations and writing I had expected a deeply thought-provoking read, but have to admit to being disappointed. There are some good points without a doubt, but the book pretty much focuses on one idea, the application of fitness functions. But I’m not convinced it warrants several hundred pages of a book as a result the point does at times feel laboured.

There are some arguments made, that leaves me thinking that there is a view that the only answer is microservices in the conventional model of Kubernetes, Docker etc, which I agree is a powerful paradigm to allow solutions to evolve, but it isn’t a silver bullet and not always right in every case (if you have a team lacking the underlying appreciation of the goals, or put in to place in an ad-hoc manner (see Chris Richardson‘s work) it isn’t going to help.

Alongside this, there is little said about the interface definition for microservices (typically APIs of one form or another). Whilst mention of leaky abstractions are made, the material illustrations such as code lead API definitions are omitted (risk being, code changes, the API changes and the impact cascades).

What surprised me the most is the on more than one occasion the books points to ERPs not being sufficiently customisable. Yet, anyone working with ERPs will tell you that ERPs are at their best when you use them to leverage industry best practices rather than crowbar them to fit unconventional ways of operating. If you’re a manufacturer, is fiscal reporting part of your differentiator; probably not, so why not take best practice OOTB.

As usual, I have mind mapped things as I read through the book.  The dynamic/interactive version is here, the image (but not in full detail) is below.

Domain Driven Design

book, Design, mindmap, Patterns

I have been wading through Eric Evan’s Domain Driven Design Book. As with many design and architecture focussed books I try to mindmap as I go so I have a quick reference resource. The mindmap for this book can be seen below and is linked to the WiseMap version which is dynamic.

In terms of of a review of the book, it contains lots of nuggets of helpful ideas and information but it is a rather heavy going to read. Some points feel over laboured such as the use of consistent language, at times it feels like half the book is dedicated to this one point. Whilst Chapter 14 – Maintaining Model Integrity sounds unadventurous as a chapter, I found this to have a lot of really helpful content such as going into the details Bounded Contexts and so on which is highly relevant to the world of microservices.

API Design

"best practise", API, apiary, book, mindmap

When it comes to ensuring I keep up good practises, I try to look at books  in areas I think I have a good handle on such as APIs.  Why?  well it confirms and validates I’m upto date; sometimes another view point can spark ideas on how to make something better, improve an approach or simply understand another way of explaining an idea.  The later is important as the key benefit of knowing something is the opportunity to help someone else. Not everyone communicates or understands ideas in the same so this is always helpful.

Designing Great Web APIsSo recently I ran through James Higginbotham’s Designing Great Web API’s book(let).  Often when goping through a book I mindmap it so that I can share it, and refer to it as a lit of prompts reminders if necessary.  Whilst’s James’ book doesnt  reveal anything new or relevatory for anyone working with APIs it does provide a good succinct explination to  basic practises. So here is the mindmap:

great APIs

You can also access my MapWise view here. James’ book can be obtained freely from O’Reilly here.

The book doesn’t go into the depth of details for practises that Apiary (Pro Edition) offers with style guidelines which will describe morec detailed recommended practises (more here).

Building Microservices

book, Microservices, mindmap, notes, Technology

When I read a technical book from cover to cover I usually build a mind map so that I can use it as a memory jogger in the future if I need to return to get key points such as arguments or facts. With the ferstive break I have had time to finish reading Sam Newman’s Building Microservices. The following is a static image, but clicking on it can take you the dynamic site provided through WiseMapping, it does take a moment or two as the map is large (or click here).

microservices

Many of the points made in this excellent book are true to software design and development generally, but given a Microservices spin. For example, monitoring and security should be incorporated into any good design.

ITSO, mindmap, Oracle, reference architecture, Strategies

So I have been chipping away at my mind mapping of the foundation reference architecture from Oracle (part of the IT Strategies from Oracle – ITSO material).  So I have recently updated the mind map.  You can see it via WiseMapping here. Navigate an image of it below (very large now).
