The AWS RI Marketplace – a ghost town ?

empty_market_by_auraomega-d81ql31

In 2009 AWS launched their EC2 Reserved Instance (RI) pricing model , providing a significant discount compared to the on-demand pricing model if you are willing to commit to 1 or 3 years of usage.

Cost management on AWS is a hot topic, with hundreds of blogs on making the right choice of RI’s. A new market of AWS cost management tools emerged, with tool vendors promising massive ROI. Based on AWS billing & usage data analysis, these tools will provide RI recommendations. AWS’s own Trusted Advisor will also provide this kind of analysis, as included in their higher level support plans.

I highly recommend my SDL FredHopper colleague David Costa’s presentation on the topic, as he basically wrote the (internal) book on how to do this at scale: Cost Optimization at Scale.

While you can shift RI reservations, after you made them;

  • Switch Availability Zones within the same region
  • Change between EC2-VPC and EC2-Classic
  • Change the instance size within the same instance type

There are several use-cases where you would want end your reservation before the reservation end date;

  • Switch Instance Types.
  • Buy Reserved Instances on the Marketplace for your medium-term needs.
  • Relocate region.
  • Bad capacity management.
  • Unforeseen business or technology changes.

DCD EMEA Awards 2016 Finalist !

Less then 24 hours after I published my ‘thank you team’ post, Datacenter Dynamics announced their nominees for this year’s DCD EMEA 2016 Awards.

I’m very proud one of the mentioned projects in my original post got nominated in the Category Cloud Journey of the Year

finalists_logos

The selected project is our move of SDL Machine Translation from our co-lo datacenter to a IAAS cloud solution;

Availability of content in multiple languages is key to driving useful international business. SDL’s Statistical machine translation delivers high quality translation services to more thousands of customers. While SDL’s research organisation already explored a new approach to machine translation, the future development and deployment needed more flexibility in technology choice and dynamic scalability to be commercially successful. Over 10 months, SDL migrated their current workload deployment consisting of hundreds of servers, without customer downtime, to a private Cloud deployment. The migration included a project team of more than 35 staff in 5 time zones. Besides flexibility and scalability gains, the migration saves SDL more than 450k GBP over 4 years.

The teams worked long hours, overcoming many obstacles a long the way. Congrats to all involved!

Seven years of Cloud experience in ten Tweets.

With AWS celebrating 10 years after the launch of Amazon S3 in March 2006 and Twitter also celebrating 10 years , I wanted to revisit my ‘cloud rules’ published on Twitter and on my Dutch blog in 2011. The original was written after 2 years working on an enterprise IT implementation of whatever was perceived ‘cloud’ in 2009, building a Gov version of Nebula (the Openstack predecessor) and starting to utilize AWS & Google Apps in enterprise IT environments.

As the original rules where published on Twitter with its 140 character limit, it lacked some nuance and context so I converted it in to a blog post. The original 7 rules from 2011, with context;

Even though the debate on a definition of ‘what is cloud’ died down a bit, it does still surface now and then. Given the maturity of the solutions , the current market state and the speed of change in the market of ‘cloud’ ,I still stick to my opinion from 5+ years ago: a generic definition of cloud is not currently relevant.

The most common used definition seems to be the one NIST (pdf) published in 2011, and provides a very broad scope. Looking at IT market development the last few years and the potential of what is still to come, we are continually refining these definitions.
As ‘cloud’ products and services pushed to the current market will be common IT practice in a few years,  we will slowly see the ‘cloud’ name being dropped as a result.

There is still a valid argument to have a common definition of ‘cloud’ and the delivery models within companies, to avoid miscommunication between IT and the business. The actual content of that internal definition can be whatever you want it to be, as long as there is a common understanding.

The definition debate in the general IT market will continue until the current hype phase has passed. As soon as we enter Gartner’s “Trough of Disillusionment” all marketing departments will want to move away from the ‘cloud’ term, and replace it with whatever the new hype is. We can already see this happening with the emergence of ‘DevOps’, ‘BigData’, ‘Internet of Things (IoT)’.

Just remember there is just one truth when it comes to ‘cloud’ ; “There is no cloud. It’s just someone else’s computer”

The new normal – Cloud & developer enablement.

48_imgAccording to AWS CTO Werner Vogels “Cloud is now the new normal.”

Where the first day keynote at AWS’s ReInvent 2015 conference was all about enabling companies to migrate their current services to the cloud, the second day keynote by Vogels was all about the ‘new normal’ – developer enablement.

With new services like AWS Snowball , AWS Database Migration Service and AWS Schema Conversion Tool , AWS tries to smoothen the migration path from old on-premise infrastructure & application deployments, to using AWS’s Infrastructure As A Service offering (EC2, RDS, VPC, S3, ..).

While these new services help companies to move to a consumption model for compute, storage and networking, it is still very infrastructure focused. Design decisions around (virtual)network layout, load balancers and the build & management of the operating systems (Windows/Linux) are still the customer’s responsibility.

Needing to still deal with all these elements, holds developers back from moving fast as they go from idea to the launch of a new service. It slows the creation of real value to the company down.

In the real ‘new normal’ world, the developer is enabled to deploy a new service by building & releasing something fast, without needing to worry about the infrastructure behind it. By stitching external managed capabilities/services together in a smart way the developer can move even faster.

Where in the past a developer would try to speed releases up by code-reuse with, for example, software libraries, the availability of developer ready services like a fully managed message queuing service (AWS SQS) or a push messaging service (AWS SNS) have enabled developers to move even faster without worrying about the manageability of the solution.

The future of datacenter build & co-lo (or CIO’s are getting out of the datacenter business – Part2)

Last year my friend Tim Crawford wrote an excellent article on why CIOs should get out of the datacenter business.  Tim focused on how current big cooperates are moving away from building, owning or renting datacenter facilities in favour of consuming IT at higher levels of the stack.

As he focused on the migration of leading big companies, it leaves the question; what about the future Fortune 500 companies?

The problem with the Docker hype

hyundai-elantra-flattened-3Remember when the Cloud hype kicked off and we all looked mesmerised at the Cloud Unicorn companies (like Netflix) that got great benefit from Cloud usage? We all wanted that so badly. We wanted to get out of the pain of high maintenance cost and the lack of agility. Amazon, Google, Microsoft Azure all seemed to provide that. Just by the click of a button.

In 2012 I did a short whitepaper on what it takes to move an application the cloud, based on my painful experience with some Enterprise IT moves to the cloud.  I stated, “The idea that one can just move applications without change is flawed.” There was not enough benefit in moving the monolithic, 10 year old, application on the cloud. That type of move may deliver small cost savings, but that is actually a hosting exercise. It could even be dangerous to move in that way because the application may not be suitable for the cloud providers’ reference architecture. That could for example lead to availability and performance issues. The unicorn benefits could only be gained if you changed your way of working and thinking.

The same goes for the Docker hype now;

I agree with all the potential that Docker unlocks; portability & abstraction. It is a game changer and some even say ‘Docker changes everything’

Hearing people talk at large conferences (like AWS ReInvent) about Docker seems like the first phase of the Cloud hype all over again. They state ‘Just docker-ize your app’ and all will be great. Sureal conversations with people that try to put anything and everything in a container. ‘Yes, just put that big monolithic app in a container’

People seem to forget that Docker is an enabler for architecture elements like portability and micro-services (that leads to scalability).

I highly recommend reading James Lewis & Martin Fowler ‘s article on microservices first: http://martinfowler.com/articles/microservices.html

Then See this:

Because The problem with the Docker hype currently? It makes it about the tool. And only the tool will not fix your problem.

Our Trust issue with Cloud Computing

Recently SDL (my employer) did a survey on customer ‘trust’ for the marketer.B0AgpWXIAAA5mZm

Being in the IT space I tend to deal a lot with ‘trust’ the last few years. Being responsible for the Cloud services delivery for my companies SAAS & hosted products we deal with clients evaluating and buying our services. My teams also evaluate & consume IAAS/PAAS/SAAS services in the market, on which we build our services.

The ‘trust’ issue in consuming Cloud services is an interesting one. IAAS platforms like Amazon abstract complexity away from its user. It is easy to consume. The same goes for SAAS services like Box.com of Gmail; the user has no clue what happens behind the scenes. Most business users don’t care about the abstraction of that complexity. It just works….

It’s the IT people that seems to have the biggest issue with gracefully losing control and surrendering data, applications, etc., to someone else. Control is often an emotional issue we are often unprepared to deal with. It leaves us with a feeling ‘they can’t take care of it as good as I can…’ Specifically IT people know how complex IT can be, and how hard it can be to deliver the guarantees that the business is looking for. For many years we have tried to manage the rising complexity of IT within the business with tools and processes, never completely able to satisfy the business as we where either to expensive or not hitting our SLA’s.

German companies ask for Internet border patrol.

border_0_0In the last year multiple companies started serving German customers out of Germany based datacenter locations.

There seems to be a specifically strong sentiment around security & privacy with German companies after the Edward Sonwden leaks. The kneejerk reaction is to mandate that servers should sit within German borders, as that would take any security & privacy concern away. Cloud providers are now starting to follow this customer demand.

Interestingly this reaction is more sentiment driven as there is no legal ground to request this. Especially as more and more German companies are putting this in place as a default policy, regardless of what type of data (privacy sensitive or not…)

Looking at the Federal Data Protection Act (Bundesdatenschutzgesetz in German) (“BDSG”) it states that certain transfer of data (like personal data) outside of the EU needs to be reported and approved and Data controllers must take appropriate technical and organizational measures against unauthorized or unlawful processing and against accidental loss or destruction of, or damage to, personal data. Nothing says servers need to be in Germany.

Looking at other EU countries, Germany seems to be the only country where organizations express such behavior. The only next inline could be Switzerland.

CIO’s plukken vruchten van server innovaties

Op de afgelopen CIO dag (Nov 25&26) in Amsterdam werd ook ‘The big data center book’ uitgereikt. Hier in werden de Data center & cloud trends voor 2013 & 2014 toegelicht.

Mijn artikel in dit boek beschreef de trends in server hardware innovaties;

Naarmate onze datacenters groter worden en de eisen van webscale- en cloudproviders de markt overnemen, worden servers meer en meer slechts een component van een grotere machine. Hoewel componenten waardevol kunnen zijn, zijn zij niet langer het hele systeem en als zodanig kan hun waarde niet los gezien worden van het datacenter waarin zij gehuisvest zijn. De efficientie van het component wordt daarmee belangrijker dan het bezitten van ‘coole features’. Wat zijn de actule ontwikkelingen die moeten zorgen voor een lager energieverbruik van servers ?
