Tale of Two Clouds: A Feature Comparison of Azure and AWS

  image

Comparing Azure and AWS is a bit like comparing apples and oranges. Each platform has features that either duplicate or overlap with features of the other platform.

In reality the focus needs to be on solving the business problem and not the technology problem. That being said a lot of companies either have both platforms or are struggling with deciding on, or moving from, one or the other.

Last night at the Nashville Microsoft Azure Users Group I presented a technical comparison of Azure and AWS features.

Despite my admitted bias towards Azure I nevertheless believe that I was pretty fair and objective. Smile

  The topics I covered were:

– Cloud Service Models
– Deployment, Management and Automation
– Compute
– Storage
– Messaging
– Email
– Networking
– Security and Identity
– Operating System & Data Transfer
– Internet of Things (IoT)
– Development Languages and Runtime Support
– Marketplaces
– Media Services
– Mobile Services
– Visualization
– Machine Learning
– Non-Technical Considerations
– Pricing Models

The deck from that presentation is in the files section of the Nashville Microsoft Azure Users Group.

The Future of Azure is Azure Stack!

image

image

I realize that the title above might be a bit controversial to some. In this blog post I will attempt to defend that position.

The two diagrams above, taken from recent Microsoft public presentations,  symbolically represent the components of Public Azure and Private Azure (Azure Stack).  If you think that they have a lot in common you are right.  Azure Stack is Azure running in your own data center.  Although not every Azure feature will be delivered as part of Azure Stack at its initial release (and some may never be delivered that way because they require enormous scale beyond the reach of most companies) , it is fair to say that they are more alike than they are different.

Back in 2012 I wrote a blog post on building cloud burstable, cloud portable applications.  My theses in that post was that customers want to be able to run their applications on local hardware in their data center, on resources provided by cloud providers and/or even resources provided by more than one cloud provider. And that they would like to have a high degree of compatibility that would allow them to defer the choice of where to run it and even change their mind as workload dictates.

That thesis is still true today.  Customers want to be able to run an application in their data center. If they run out of capacity in their data center then they would like to shift it to the cloud and later potentially shift it back to on-premises.

That blog post took an architectural approach using encapsulation and modularity of design to build applications that could run anywhere.

The Birth of Azure

A bit of additional perspective might be useful.  Back in 2007 I was working as an Architect for Microsoft and I came across what would eventually become Azure. (In fact that was before it was even called Azure!) I had worked on an experimental cloud project years before at Bell Labs called Net-1000. At the time AT&T was planning on turning every telephone central office into a data center providing compute power and data storage at the wall jack.  That project failed for various reasons some technical and some political, as documented in  the book The Slingshot Syndrome. The main technical reason was that the computers of the day were minicomputers and mainframes and the PC was just emerging on the scene.   So the technology that makes today’s cloud possible was not yet available.  Anyway, I can say that I was present at the birth of Azure.  History has proven that attaching myself to Azure was a pretty good decision. Smile

The Azure Appliance

What many do not know is that this is actually Microsoft’s third at tempt at providing Azure in the Data Center. Back in 2010 Microsoft announced the Azure Appliance which was to be delivered by a small number of Vendors . It never did materialize as a released product.

Azure Pack and the Cloud Platform System

Then came Windows Azure Pack and the Cloud Platform System in 2014 to be delivered, also in appliance form, by a small number of selected vendors.  Although it met with some success, is still available today, and will be supported going forward, its clear successor will be Azure Stack.   (While Azure Pack is an Azure-like emulator built on top of System Center and Windows Server Azure Stack is real Azure running in your data center.)

Because of this perspective I can discuss how Azure Stack is Microsoft’s third attempt at Azure in the Data Center and one that I believe will be very successful. Third times a charm Smile

Azure Stack

The very first appearance of Azure Stack was in the form of a private preview, and later a public preview: “Azure Stack Technical Preview 1”.  During the preview it became clear that those attempting to install it were experiencing difficulties, many of them related to the use of hardware that did not match the recommended minimum specifications.   

Since Azure Stack is so important to the future of Azure Microsoft decided to release it in the form of an Appliance to be delivered by three vendors (HP, Dell & Lenovo) in the Summer of 2017.  According to Microsoft that does not mean that there will be no more technical previews, or that no-one will be able to install it on their own hardware.   (It is generally expected that there will be additional Technical Previews, perhaps even one at the upcoming Microsoft Ignite! conference later this month.) It simply means that the first generation will be released in controlled fashion through appliances provided by those vendors so that  so that Microsoft and those vendors can insure its early success.

You may not agree with Microsoft (or me), but I am 100% in agreement with that approach.  Azure Stack must succeed is Azure is to continue to succeed.

Microsoft Virtual Academy’s new more agile approach to Azure IT Pro training.

image

Microsoft Virtual Academy is launching a new series for IT Pros that will be delivered in smaller replaceable chunks that will be more consistent with how Azure Features are delivered, rather than long recorded units that are obsolete by the time they are released.  This will be a more agile approach.

They have already released several samples published today (I understand that some of the demos will be added later):

They made the point in the launch event today that that the Azure Active Directory unit was made obsolete last night by the move of Azure Active Directory into the “Current” portal from the “Classic” portal. They will replace that unit and re-release it soon. Just one example of their new agile approach.

Although this series is for “IT Pros” I suspect that they will take the same approach for Developers soon if this works out.

My Favorite Azure References

image

  In my “day job” as an Azure specialist I am often asked for Azure references on various topics. Here is a list of some of the most important references that I have been sending out recently:

Sizes for Windows virtual machines in Azure and Sizes for Linux virtual machines in Azure cover the specifications of the VM sizes that you can run in Azure:

Microsoft server software support for Microsoft Azure virtual machines covers what is (and is not) supported running in an IaaS VM:

Cloud Platform roadmap covers what has been recently released and what Microsoft is working on. 

Microsoft Azure and Amazon Web Services covers AWS Compete is a good reference to have if the question of comparing AWS and Azure features comes up.

One additional great resource is the Azure Learning Paths.  Azure is so broad that it is difficult to know where to start learning about a particular service or feature. The Learning Paths are step-by-step flowcharts that guide you through the documentation and videos on about 35 of the Azure services. (Not every service is so documented, but the ones that are are well done.) Highly recommended.

Azure at //Build 2016

The dust has barely settled on //Build 2016; one, of the two premier annual Microsoft conferences: //Build and Ignite!  For those of you who not aware of it these two conferences morphed from two earlier Microsoft conferences.

//Build is the successor to the earlier Professional Development Conference (PDC).  That conference was targeted mainly at developers. It is still primarily for developers.

Ignite! is the successor to the popular Microsoft TechEd conference. It was targeted mainly at IT Infrastructure types.  Ignite! still maintains that focus.

However, in this day and age of DevOps the lines between the two constituencies are blurring quite a bit.  There is often something for each in both of these conferences.

Although Ignite! is scheduled for September 26th in Atlanta this time //Build 2016, held in San Francisco at the end of March, has just passed by.

There were a large number of announcements at //Build 2016.  Here is a brief summary of the ones that I feel are most important to the Azure community. (There were also a  large number of non-Azure related announcements; but I will leave those for someone else to catalog. Smile)

Here is my top 10:

  1. Azure Functions PaaS Preview (Server less computing/AWS Lambda Compete)
  2. Virtual Machine Scale Sets General Availability (Autoscaling without pre-creating VMs)
  3. Azure Service Fabric General Availability (A hyper-scale successor to Cloud Services)
  4. Storage Service Encryption Preview (Encryption for Blob Storage rest.)
  5. IoT Starter Kits & the IoT Gateway SDK
  6. Document DB Mongo API Support Preview (A widely used NoSQL database) 
  7. Import/Export up to 8TB
  8. U-SQL for Data Lake (A new SQL Like language for Big Data)
  9. DevTest Labs enhancements
  10. PowerBI Embedded Preview

There was an excellent Day 2 keynote by Scott Guthrie recorded and available on Microsoft’s Channel 9 video site.  There are also a large number of session videos posted there so that, even though you did not get to actually go to //Build, you can take advantage of them. You can find one on any of the topics above, and more.

Enjoy

Disaster Recovery: Asking the wrong question?

image

In my role as an Azure specialist I get asked a lot of questions about Disaster Recovery. IMHO they almost always ask the wrong question.

Usually it goes something like “I need Disaster Recovery protection for my data center. I have N VMs to protect. I have heard that I can use Azure Site Recovery either to facilitate Disaster Recovery to my backup data center, or even use Azure as my backup data center.” That is true. Smile

In a previous lifetime I used to work on a Disaster Recovery  testing team for a major New York based international bank. We learned early on two major principles:

1. It is all about workloads since different application workloads have different Disaster Recovery  requirements. Every workload has unique Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO). Not all workloads are created equal.   For instance email is a critical workload in the typical enterprise. An outage of more than a few hours would affect business continuity significantly.  Other application workloads (such Foreign Exchange Trading, Order Processing, Expense Reporting, etc.) would have more or less stringent RTO and RPO requirements.

2. So it is really is all about Business Continuity. Disaster Recovery is a business case. It is clear that providing perfect Disaster Recovery for all application workloads would be extremely expensive; and in many cases not cost effective. In effect there is an exponential cost curve. So it is all about risk management and cost/benefit.

So where does that leave us?

1. Evaluate your Disaster recovery requirements on a workload by workload basis

2. Plan how to implement it considering the objective of Business Continuity, RTO and RPO.

3. Use Azure Site Recovery to make it happen. Smile
