This week's newsletter is all about the benefits and risks involved in storing your sensitive business data in the cloud using a public cloud service like Microsoft Azure. We welcome Greg Schulz, Founder and Senior Analyst of StorageIO, who will help us explore this topic in his guest editorial for this issue of WServerNews. Greg is also an author of several excellent books and you can read my reviews of them in the Recommended For Learning section of this issue. Plus we also have the usual news, tips, tools and fun stuff so be sure to read it all!
Storage is of course a valuable commodity in the IT world, but what can you do when you run low on storage? One solution is to reclaim it by deleting files that are no longer needed, and that's just what the IT guy did for Dilbert when he asked for more email storage--but it didn't turn out the way Dilbert had expected:
Yes you certainly can't please everyone, can you?

Cloud storage considerations
Let's now move on to our guest editorial by Greg Schultz which is actually an abbreviated version of a much longer article that Greg contributed to my column on CloudComputingAdmin. The article will be published soon and when it appears I'll mention it here in this newsletter.
And now here's Greg...
Using Microsoft Azure for cloud storage
Let's say that you have been tasked with, or decided that it is time to use (or try) public cloud storage such as Microsoft Azure. Ok, now what do you do and what decisions need to be made? Keep in mind that Microsoft Azure like many other popular public clouds provides many difference services available for fee (subscription) along with free trials. These services include applications, compute, networking, storage along with development and management platform tools.
Microsoft Azure besides offering cloud storage also has services for:
- Compute (where you can run your applications, containers or virtual machines)
- Web and Mobile along with Developer and other tools
- Analytics for little and big data along with Networking
- Media and Content Distribution Networks (CDN)
- Identity and Access Management (IAM) & Security
Microsoft Azure cloud storage services include:
- Azure search and StoreSimple cloud gateway appliance
- SQL Database and DocumentDB (NoSQL) and SQL Data Warehouse
- Files (preview) -- Accessible within Azure cloud or via external REST API
- Queues and Redis Cache and Tables
- Storage Blobs (Block blobs, append blobs and page blobs)
- Premium storage (preview) -- Non-blob block storage accessible within Azure cloud including HDD and SSD based storage for virtual machines
So which Microsoft Azure cloud storage service do you need or want to use?
There are many different options, however if you know what you need, then it's a simple matter of understanding what the options are and aligning those to your needs. Unless you already know which service that you need to use, let's take a look at your options to help with Azure storage decision making. Let's review what are your applications server, storage and I/O Performance, Availability, Capacity and Economic (PACE) characteristic requirements among others. Selecting cloud server, storage I/O resources along with application functionality is similar to selecting physical resources and traditional software. Keep in mind that you may require more than one type of data and storage services as everything is not the same including across, as well as within different applications.
Understanding your application and environment needs for cloud storage involves making decisions in the following areas:
- Application focus: How will your application use data storage (activity and access)
- Availability: How resilient and protected does your data storage need to be
- Capacity: How much data do you need to store and access
- Economics: How much will it cost up-front and recurring, what's your data value
- Location matters: How far is your application from the data
- Management: How will you management, protect, preserve and server data
- Performance: How much performance do you need
Let's explore a few of these decision areas in more detail. [Editor's Note: You'll be able to read Greg's full article when it's published in my column on CloudComputingAdmin.com]
How will your application use data and storage, for example, does it need access to an SQL Server (or NoSQL) database or data warehouse? Do you simply need storage to create a database, key value, an object or another repository on? Do you need storage space for placing active changing data, or data that is static, write once read many (WORM) and immutable? Do you need fast low-latency storage close to where your application resides or do you need lower cost, high capacity storage with good durability? How will your applications access and use the data and storage? For example via database SQL or ODBC, using XML, JSON, S3, Swift, CDMI among other APIs and programmatic bindings, using file shares such as NFS or CIFS/SMB or HDFS (Hadoop Distributed File System) or simply as a block or blob of storage? Or will your application need to access message queues and simple key value tables? Think of it this way, if you were adding new storage on-site, what would you be looking at doing? Buying a dedicated or shared block SAN type storage system, or an NAS for file and data sharing, object storage, database server or something else?
Where will or does your application reside, within Microsoft Azure running on a cloud server instance, or, on premise at your own (or somebody else's) site outside of the Azure cloud running on a physical, virtual or other cloud server instance? The reason location of your application matters is that like other cloud service providers such as Amazon Web Services (AWS), Google, HP, IBM/Softlayer, Rackspace, VMware vCloud among others, some storage services are restricted to use within their respective clouds, while others can also be accessed externally. For example, higher performance cloud storage services such as premium (HDD and SSD) storage is only available within and from Azure instances. This is similar to AWS Elastic Block Storage (EBS) among others. On the other hand, storage blobs (e.g. buckets and objects) are accessible internal, as well as external to the Azure cloud similar to AWS Simple Storage Service (S3) buckets and objects, or Google Cloud Storage (GCS) containers and objects among others. Thus, the importance of knowing where your application currently runs and will be accessing storage is important for cloud storage decision making.
What level of performance do you or your applications need? This will depend on if you are looking to use Azure storage for bulk storage of data such as videos, images, photos, audio recordings or other large (and small) static data, or if you need storage with transaction ability to support many reads or writes. Location matters with performance, the closer your application is to the data, or, your data and storage are to the applications the better. For example, there are Azure premium storage services including with fast flash-based Solid State Device (SSD) as well as HDDs. However, those services need to be accessed from within Azure. Understand what your applications need for latency or response time, as well as in terms of messages processed, reads and updates, as well as IOPs, to help determine the applicability of different Azure services. Note that various Azure data and storage services have limits on performance activity in terms of bandwidth, IOPs, transactions, reads, writes, Gets, Puts and other operations, understand what they are vs. your application needs to design and decide appropriately.
Don't be scared of clouds or Microsoft Azure storage options, instead, be prepared, and know how to navigate your various options to meet your specific needs and requirements. Shopping for and evaluate cloud storage options is similar to what you would (or should) do for acquiring traditional physical storage. Granted, some of the names, terms, and access technologies will be different. Learn more about Azure, along with data and storage options here as well as at my blog:

Recommended for Learning
This week I'll be briefly reviewing two CRC Press titles authored by Greg Schulz who contributed the guest editorial for this issue of WServerNews.
Cloud and Virtual Data Storage Networking
This book is an excellent read for business and IT decision makers (BDM/TDM) who want to get the big picture of where enterprise storage is going these days. The book covers both traditional on-premises storage solutions and newer, converged virtualized network and cloud storage solutions. Connectivity, management and protection strategies are described in some detail at a level that both the non-technical BDM reader can understand while digging deep enough into technologies to provide a good foundation for understanding by TDM audience. Chapters can be read in sequence or as needed to enhance your knowledge of a particular aspect of cloud and virtual data storage. Organizations who are planning on deploying, enlarging or replacing storage solutions will benefit from the chapters and sections that deal with strategic planning issues which will help them both to clarify their goals and to identify the technologies they can use to help them achieve their goals. You can buy this book on Amazon here:
The Green and Virtual Data Center
This book takes a level-headed look at the promise and hype surrounding "green" computing and examines both the myths and realities of why and how datacenters can be made more "green" both in an environmental sense and in terms of economics. A major portion of the book is devoted to understanding the virtual datacenter, something that was still relatively new in 2009 when the book was published but which is fast becoming the norm today for datacenters. The book also provides detailed coverage of the various technologies that make green and virtualized datacenters possible, and though there have been a few significant technological advancements (e.g. the rapid increase in size and decline in cost of enterprise SSDs) in this area since the book was published, the vast majority of technologies needed to build and maintain green/virtual datacenters are standardized and have only evolved minimally, so organizations who plan to deploy, build out or replace their existing datacenters with green/virtual technologies can benefit well from giving Greg's book a thorough read.

AD - Planning for disaster recovery
Does your organization need to develop a plan that will enable them to recover their Active Directory forest in the event of a disaster happening that impacts all of your domain controllers? A good place to start is the Planning for Active Directory Forest Recovery guide which is available from the Microsoft Download Center here:
And if you're a Microsoft Premier customer you should also ask your TAM for information about the Active Directory Recovery Execution Service (ADRES) offering delivered by Premier Field Engineers.
AD - Cannot forcibly disjoin from domain
If you need to forcibly remove a member server from a domain you can usually do so using the netdom remove /force command. This can be useful for example if the domain the server thinks it is joined to no longer exists because of all domain controllers for the domain being lost or demoted. We have heard however of at least one occasion where this command didn't work, possibly because of some registry corruption on the affected server. What did work in this scenario was to start by disabling all of the network connections on the server and then run the netdom command using local admin credentials e.g. .\Administrator for the username.
ConfigMgr - Exclude MAC Address from being registered during imaging
Here's a tip from Matt Tinney showing how you can exclude a MAC address from being registered to a machine during imaging with SCCM by adding it to this multi-string registry key:
This is useful for a dock or Ethernet dongle that is used to image tablet devices.
