Review of Open2Study’s “Introduction to Enterprise Architecture”

image

Recently, I took an online training course provided by Open2Study – an open learning initiative by Australia’s Open Universities. Its title was an “Introduction to Enterprise Architecture” and I’m providing an overview and review of it.

Course Logistics

Firstly, the course is free – all you need to invest is about 10 hours of your time over a month. From what I can see, the course runs every four or five weeks. You can find all the information at this web page: https://www.open2study.com/courses/introduction-to-enterprise-architecture

Course Delivery

Open2Study deliver the course online over four weeks – not a single lazy Sunday afternoon when you can rush through it – using ten minute YouTube videos. Each video ends with a “pop quiz” and each module ends with an assessment. They each use multiple-choice questions, but as I’ll comment later that doesn’t make them easy.

Craig Martin presents the videos and in my view is the best person in the world to teach you about enterprise architecture. I’ve linked to an overview about him here. http://enterprisearchitects.com/learning/instructors/craig-martin/  I first knew about him after finding some videos on YouTube about similar subjects and realised how much I liked his teaching style.

“Real enterprise architecture”

Very quickly you realise this course is about enterprise architecture – the discipline of making businesses more effective, and not enterprise IT architecture – dealing with large numbers of IT systems.  Expect to learn about business processes, business capabilities and industry reference models – rather than how networks or servers work.

I’d say about 30% of the content discusses “traditional IT”, the remaining 70% is about business architecture and how to implement transformational change within a business.

If you want to learn how to design technically large and complex IT systems – look elsewhere.

If you want to know how deliver business value and business transformation using IT, read on.

Seven out of ten

Having completed, and passed, the course I’ve given the course a score of 7/10. To understand why, I’ve broken my score into 7 good points and 3 bad points:

Good points

  1. The course was about “proper” enterprise architecture and not advanced IT design – previously I’ve found these types of courses always end up swaying towards just IT or just project delivery techniques
  2. I actually learned, a lot.  Too often we find ourselves sat in training where we know more than half of the material already but we have to sit through it to learn the bits we don’t know.  I’d estimate I knew about 20% of the training material before I started.
  3. The ten minute videos were just long enough to cover a complex subject but short enough so I didn’t get bored and just listen to it in the background.
  4. The videos each had a transcript that you could read either in sync with the video or without watching the video at all – sometimes I needed to read what had just been said slowly to understand it said rather than listen to it again.
  5. Craig Martin’s delivery used straight forward real world examples to compliment his academic material – sometimes instructors get carried away telling you long and complex stories rather than just the relevant details
  6. The videos used a clever “transparent whiteboard” to draw diagrams that allowed me to take good screenshots for my notes – there’s no slides for this course.
  7. The web site was easy to use – sadly that still has to be said and not taken for granted.

Bad points

  1. The course was both an introduction to enterprise architecture and an introduction to TOGAF.  Although there’s four modules to cover both of these topics it’s a lot of material for “an introduction”.  The pace in module 2 that went through TOGAF in quite some detail meant a lot of stopping to catch up on my notes and then work out what was just said.  A slowdown in pace at the expense of some content would’ve been better.
  2. The questions in the pop quiz at the end of each module weren’t always covered in the video!    The difference in terminology or even material often meant I had a blank face when I read the questions, that didn’t help morale after a hardcore module.
  3. The lack of download materials obviously helped keep the training free but also made it hard to do any “offline” studying.

Overall : Recommended

A few new IT/EA architect blogs

 

I’ve previously written about my habit of reading blogs/RSS feeds related to IT and enterprise architecture, and wanted to share/promote a couple more that have joined my reading list lately.

  • The Value Realization Blog from Microsoft
    I think I’ve written about this before but it’s worth mentioning again – a great place to learn about communicating and managing value to IT leaders, in this case written in the context of Microsoft consulting engagements.
    http://blogs.technet.com/b/valuerealization/

  • J. D. Meier’s blog at MSDN
    It’s purely coincidence that this blog is hosted by this guy’s employer – Microsoft.  His blog article titles include topics such as: 10 high-value activities in the enterprise, success articles for work and life, and Agile and the definition of quality.  A very senior architect at Microsoft who shares his wisdom about delivering quality solutions.   http://blogs.msdn.com/b/jmeier/

 

  • J. D. Meier’s personal blog
    Putting the constraints of his day job to one site, J. D. again shares his experience about helping people “get better results in work and life”.  http://blogs.msdn.com/b/jmeier/

 

  • Enterprise Architect Voices
    A syndicating site that everyday collects a broad range of articles relating to enterprise architecture.  One in ten will jump out as a must-read while the rest help you understand “what other people need to read about for their jobs”  http://eavoices.com/

New online resources for architects from Microsoft

image

Those who’ve read my previous blog articles, or who know me, know my frustration at finding good educational resources for IT architects.  I’m not an enterprise architect or a senior developer, yet a lot of “architect” resources online are for just those audiences.

 

Microsoft’s older architect resources

About 10 years ago, Microsoft started publishing a lot of good academic material for IT architects.  This is the type of material that doesn’t really age, unlike technology specific resources, but for many reasons it started to disappear, not get updated, or not get added to.  Then the .net era took off and their attention shifted to the developer audiences.  You can find what remains online here.

 

Three great new architect resources from Microsoft

Very recently, some good new technology agnostic IT architect resources started appearing on Microsoft’s web sites.  I found them through the MSDN and TechNet blog RSS feeds I scan through every day and wanted to share them further.

The Value Realization blog

This blog compliments an enterprise strategy service that Microsoft Consulting Services offer their enterprise customers BUT the descriptions of the services it provides are useful to ALL IT architects.

Even though this blog uses the context of enterprise IT strategy guidance to CIOs – the same guidance can apply to your much smaller project that only has two or three stakeholders and a single sponsor.  The same processes for identifying, communicating, and measuring should still apply to your project as it does to an enterprise wide strategy.  Lots of good information here – thank you Microsoft for sharing!

Link to it here.

The Microsoft Architecture mini-site and blog

A key skill as an architect is knowing what other architects know even if it’s not your domain area.  For example, it’s useful to know that the key trends in IT right now are cloud, big data, enterprise mobility, and enterprise social media.  Knowing what our peers are working on stops us working in a silo and making decisions that could hinder future integration or re-use.

The blog and blueprints section of this mini-site are excellent technology agnostic (I know they’re not vendor agnostic!) resources for key architectural trends right now.

Link to the blog here and the mini-site here.

 

The Microsoft Virtual Academy architect training

The free online training resource provides the equivalent of a day’s training about one of many architecture processes and using it to scope Microsoft product based solutions.  There’s a lot of pre-sales content in there, but if you’re not interested in that it’s worth skipping through to learn about generic architecture concepts.

I wouldn’t call it enterprise architect training like Microsoft have, but for someone in the Microsoft technology space and new for the IT architect world it’s a good resource:

Significant licensing changes in SQL Server 2014

Thanks to Mary Jo Foley of ZDNet’s tweet earlier (@maryjofoley) I’ve just read the SQL Server 2014 Licensing Datasheet and confirmed there’s two significant licensing changes for SQL Server 2014.

 

More memory in standard edition

Although we rarely see standard edition used in tier-1 deployments now, in SQL Server 2014 the database engine can support 128GB of memory.  This is an increase from 64GB, that was often seen as too low a ceiling for modern deployments – although we could discuss whether that’s right or wrong for several hours.

 

High availability deployments now require Software Assurance

This change sneaked in but it’s there in the licensing data sheet.  For now I’m just going to draw your attention to it and let the community digest.

Licensing for High Availability

SQL Server software can be configured so that if one server fails, its processing will be picked up, recovered and continued by another server. Beginning with SQL Server 2014, each active server licensed with SA coverage allows the installation of a single passive server used for fail-over support.

  • The passive secondary server used for failover support does not need to be separately licensed for SQL Server as long as it is truly passive. If it is serving data, such as reports to clients running active SQL Server workloads, or performing any “work” such as additional backups  from secondary servers, then it must be licensed for SQL Server.
  • The active server license (s) must be covered with SA, and allow for one passive secondary SQL Server, with up to the same amount of compute as the licensed active server, only.  

You can download the licensing guide (it’s only a 3 page document) from here.

How to be a better architect – what should I do? Part 2/2

 

 

This follows part 1 of this article available here.  I recommend reading them in order!

In part 2 , I look at what initial steps you can make in your career journey from “technical solution designer” to “IT architect”.

 

Phase 1 – Looking at what you already do in another way

How you already work can probably be formally defined as a technology agnostic framework using architecture terminology.  Unless you’ve become familiar with architecture terminology you may not appreciate the structure and rigour around what you hopefully do already. 

For example, I didn’t realise my design methodology used waterfall principles for years after I’d started using it. And , once I’d read ISO42010, I started to see my architecture reports contained views using viewpoints.  

Despite this “what you’re doing already is a good start” phase, a lot of people feel the need to replace how they work today with a formally defined enterprise architecture framework as that will improve how they work.

The reality probably is that how you work today is probably the best way for you to be working….for now, you just haven’t formally defined how you work before.

Once how you work is defined and documented – even just in diagrams created in Visio, you can then look at the gaps, weak points and areas to optimise.  For example, is most of your effort spent in the solution design phase but little in mapping design decisions to a specific business requirement – or do you skip the business requirements analysis phase altogether?

Finally, once you have how you work documented in IT architect terminology, you can describe how you work to another IT architect in a universal language you both understand.

 

Phase 1 Resources

Everyone has their own preferred books and articles that help them, but these are mine relevant to this phase:

12 Essential Skills for Software Architects
http://www.amazon.co.uk/12-Essential-Skills-Software-Architects/dp/0321717295

Software Systems Architecture: Working With Stakeholders Using Viewpoints and Perspectives
http://www.amazon.co.uk/Software-Systems-Architecture-Stakeholders-Perspectives/dp/032171833X/

Design, Build, Run: Applied Practices and Principles for Production Ready Software Development
http://www.amazon.co.uk/Design-Build-Run-Principles-Development/dp/0470257636/

 

 

Phase 2 – Changing the purpose of your solutions

 

The second phase I’m going to discuss is one of the hardest I went through in my transition to becoming an IT architect – respecting the fact that very few outside of the IT department have any interest in anything technical. 

The best quote that helps me remember this was someone telling me “The only person who cares about downtime is the person who pays the electricity bill.”  The only thing anyone outside of IT cares about is business outcomes and business metrics – orders per hour, £revenue per hour, website registrations per day, profitability, costs etc. 

You may start to say you have no idea how much money your system generates, how much operating your system costs, but that doesn’t mean you can’t talk about the impact your system has on business outcomes.

By the way, I’m not suggesting you change what your solutions do – just how you describe them to new audiences.

 

Elevator with the CEO question

If you’re in the elevator with the CEO for 20 seconds and he asks you what you do say

a) I’m designing some software to connect our web and ordering systems

b) I’m one of your IT architects

c) I help us use technology to sell more clothing

The answer jumps out at us when we read the three options, but did the same answer flow naturally out of your mind?  Of course, you shouldn’t give the same answer to everyone in your organisation, but you can start to see the change in thinking when you describe what you do to people outside of IT.

The same approach needs to be taken when we consider what the goals of our solutions are.  Could you describe anything you’ve done recently as:

  • enabling existing product digitalisation by integrating with social media
  • increasing IT’s agility by using cloud services
  • reducing operating costs through consolidation or standardisation

Those three statements might sound non-specific to you, but they’re messages that your boss and your boss’s boss will be glad to hear as they will help everyone to understand how you’re helping the business grow, not just keeping the same old wheels turning.

 

Phase 2 Resources

Finally, I’m going to share two useful books that helped me transition this phase, I hope they’re useful to you too:

How to be a better architect – what should I do? Part 1 of 2

 

Recently, I’ve been asked by several people about how to develop their IT architect skills further as they transition from being a “technical consultant” or “technical solution designer” into more formal IT architect roles.  Hopefully my own views in this article will help people when looking for that guidance.

 

It’s different to learning another technology or just another skill

With technical subjects, it’s mostly the case that you can read a book containing facts, start using those facts, and how you then use them is either right or wrong.  Although there’s some leeway for misinterpretation, ultimately technical things work or they don’t.

With IT architect skills, you need to take an education and experienced based approach to achieving what you want to achieve but you’ll do it your own way that suits the environment you’re in.  One person’s perfect way can be the most un-suitable for another etc.  That’s why when you take senior IT architect certifications, you have interview boards rather than exams as the best way of working is sometimes contextual.

 

That annoying gap between “technical designer” and “enterprise architect”

When you start searching for IT architect resources, like me you’ll probably start to realise most books, presentations, blog posts and guidance drop into one of two buckets:

  • Technical solution designer – someone who makes a combination of technology components meet functional and non-functional requirements yet has no need to explain the solution’s benefit in non-technical terms to non-technical leadership.  At this stage of solution design, business metrics such as revenue, costs, margins and profitability are rarely discussed.

 

  • Enterprise architect – someone who helps a business achieve its organisational goals through the use of technology and business processes – and who’s audience is typically the organisation or business unit’s executive leadership.  At this stage of solution design, justification for any solution is all about business metrics and business outcomes.

      By the way, if you now realise you work in an organisation where “enterprise architects” design only technical solutions that involve systems of systems or large numbers of servers I recommend reading the Open Group’s definitions available here.  It’ll help you understand for example how using Twitter Direct Messages to sell your company’s services is a big consideration for some EA’s right now. 

      Education for Technical Solution Designers

      As technical solution designers we were used to learning how infrastructure components, software code or software products are implemented successfully.  Typically, a solution couldn’t be considered complete until all of its components were working and users got the results they expected.

      The education resources for this area are mainly vendor training courses and academic guidance based on software engineering.  As we can all probably testify, for this stage of career development, these resources are fairly effective.

       

      Education for Enterprise Architects

      With our other example enterprise architects, you’ll start to find mention of formal enterprise architecture frameworks.  These allow an organisation to manage its business transformation and have names such as TOGAF, DoDAF and PEAF. 

      These are usually only seen in large organisations or projects wanting to implement an end-to-end framework for many architects that need to co-ordinate their activities.  They need something that has been validated time and time again and is suitable to manage critical business changes in large organisations.  However, they can struggle to scale downwards to small teams traditionally focussed on deploying technology solutions.  Even worse, they can be overwhelming for individuals looking for their first formal architect training.

       

      So what fills that gap?

      I like to think of the gap we’ve just identified as being where infrastructure, software, information and business architects find their feet.  There’s no reason why people doing these roles cannot have successful and senior careers.  The internet would make us think we all need to become enterprise architects or we’ve failed – not true.  It’s true that enterprise architects routinely have conversations with senior business leaders but when a data centre needs re-locating only an experienced and senior infrastructure architect will get the project completed.

      Let’s looks at version 2 of the figure shown above:

      image

       

      I’ve used IASA’s definitions here, other groups have slightly different names for slightly different roles.  Either way, you can hopefully see something Google searches won’t easily show you! 

      The question you probably have now is what kind of architect am I?  Well my advice is don’t worry about that for now.  Your “technical solution designer” skills right now are your strongest tools in your armoury for good reasons

      Part two of this article will look at how you can start adding additional tools, skills and knowledge to your existing way of working to start demonstrating your value in new ways to new audiences.

      Oracle pricing in Azure – who’s the target market?

       

      Overnight, Microsoft released the General Availability pricing for Oracle software provided inside Windows Azure virtual machines.  For those not familiar with Oracle’s licensing rules, traditionally its been infamous for being very un-friendly in virtual and cloud environments.  As a result, I imagine the number of Oracle deployments in virtual let alone cloud worlds has been significantly lower than its competitors, most significantly Microsoft.

       

      Initial public pricing

      The table below is a quick summary of the current Microsoft SQL Server and Oracle Database Server software licensing costs when you buy your licensing from within the Windows Azure:

      A few initial observations and thoughts

      When I compared Microsoft SQL Server’s pricing next to Oracle’s,  a few things jumped out at me straight away:

      • Oracle are keen to get into the small footprint database server market – being roughly 30-50% cheaper than SQL Server for a 1 core VM is an interesting move
      • Microsoft are keen to get larger VMs running SQL Server enterprise edition in Azure – the price differences are almost minimal between the 1 and 4 core VM options
      • Even in the cloud, the cost of Oracle’s enterprise edition has never been an issue for its target market.  What I mean by that is that application systems that use the enterprise edition of Oracle’s database server software are so large the cost of the database server software becomes less of a competitive component.
