Today cloud computing facilitated by virtualization continues emerging as the service delivery vehicle for IT to shorten go-to-market while facing unpredictable data patterns and workloads. The increasing complexities and growing user expectations make system management on the center stage of a cloud computing solution. In addition to automation, we now need a self-service model to fundamentally reduce the cost structure of required training and on-going maintenance. Besides processes and procedures, we now need work-flows and orchestration. The requirements for a management solution are now the abilities to identify and manage resources deployed to heterogeneous virtualization platforms in hybrid scenarios of cloud computing with predictability and repeatability. A single and unified platform with a consistent user experience to manage all IT resources including physical, virtualized, private cloud, and public cloud resources becomes critical for increasing efficiency and reducing TCO at the same time. From a deployment point of view, the abilities to deploy: OS to bare metal, virtual machines to virtualization host groups, and services to a private cloud signify the arrival of deployment as a service. And VMM 2012 implements and proves this concept.
Deployments, from bare metal to a service to a target private cloud, can now be available on demand with VMM2012 private cloud fabric. And IT professionals must recognize that it is no longer about configuring servers and setting up networks, it is all about delivering a requested application to target users on demand, i.e. as a service, with security and governance to timely and even proactively respond to a market opportunity.
Installing OS to Bare Metal
VMM 2012 introduces the concept of private cloud fabric. When adding a Hyper-V host to fabric from the admin console of VMM 2012, as shown on the left, one noticeable option is to provision a physical computer as highlighted below.
This capability enables VMM 2012 to identify hardware, install OS, enable Hyper-V role, and add the machine to a target host group with streamline operations in a highly automated fashion. VMM 2012 can now deploy an application as a service to a target private cloud on demand by applying an associated service template, so long a request is within its SLA and the authorized and available physical capacities are sufficient.
Notice that PXE capability plays a key role and is an integral component of the Server pool, one of the three resource pools encompassing private cloud fabric. PXE servers are to be put in place as part of remote management infrastructure to support bare metal deployment. Target hardware will need to have Baseboard Management Controller (BMC) supporting an out-of-band management protocol like IPMI, DCMI, or SMASH. The hardware specifications for remote management are beyond the scope of this article. They are briefly mentioned here for completeness.
Deploying Service to Private Cloud
In VMM 2012, deployment operations are amazingly simple. To deploy an application architecture with a running instance of a target application as a service to a target private cloud can now be simplified and easily carried out with a few mouse-clicks from with VMM 2012 admin console or System Center App Controller 2012. The below screen capture shows a self-service user using App Controller to deploy StockTrader as a service to a target private cloud. The magic is in the so called Service Template. The concepts, processes, and operations to deploy a Service Template is detailed in part 3 of the blog post series, System Center Virtual Machine Manager (VMM) 2012 as Private Cloud Enabler.
Beginning of ITaaS
There is no doubt that from bare metal to a private cloud, a management platform like VMM 2012 offers many advantages including simplicity in operations, consistency in user experience, predictability of a deployment to increase IT efficiency and reduce TCO at the same time in the long run. In this article, I single out VMM 2012 since it is an enabler of private cloud and covers much of infrastructure management. Let's however be clear. A comprehensive and agile private cloud solution must address the entire subject domain of system management in cloud computing. And that encompasses application management, service delivery automation, and infrastructure management. To form a comprehensive management solution, there are additional components in System Center 2012 including: Configuration Manager, Data Protection Manager, Operation Manager, Orchestrator, Service Manager, etc. to fully address all three areas. VMM 2012 is nonetheless a strategic starting point, a beginning of the long-waited delivery of IT as a Service.

Adding public cloud resources to an existing application can be a daunting process. The tools that you currently use to manage the software and hardware outside the cloud aren’t always the best tools to efficiently grow into the cloud. All of the major configuration management tools have cloud orchestration plugins that can be leveraged, but there are also cloud-native tools that can dramatically improve the efficiency of managing your application lifecycle. In his session at 18th Cloud Expo, ...

Let's just nip the conflation of these terms in the bud, shall we?
"MIcro" is big these days. Both microservices and microsegmentation are having and will continue to have an impact on data center architecture, but not necessarily for the same reasons. There's a growing trend in which folks - particularly those with a network background - conflate the two and use them to mean the same thing.
They are not.
One is about the application. The other, the network. T...

This is a no-hype, pragmatic post about why I think you should consider architecting your next project the way SOA and/or microservices suggest. No matter if it’s a greenfield approach or if you’re in dire need of refactoring. Please note: considering still keeps open the option of not taking that approach. After reading this, you will have a better idea about whether building multiple small components instead of a single, large component makes sense for your project. This post assumes that you...

Before becoming a developer, I was in the high school band. I played several brass instruments - including French horn and cornet - as well as keyboards in the jazz stage band. A musician and a nerd, what can I say? I even dabbled in writing music for the band. Okay, mostly I wrote arrangements of pop music, so the band could keep the crowd entertained during Friday night football games. What struck me then was that, to write parts for all the instruments - brass, woodwind, percussion, even k...

Sharding has become a popular means of achieving scalability in application architectures in which read/write data separation is not only possible, but desirable to achieve new heights of concurrency. The premise is that by splitting up read and write duties, it is possible to get better overall performance at the cost of a slight delay in consistency. That is, it takes a bit of time to replicate changes initiated by a "write" to the read-only master database. It's eventually consistent, and it'...

Keeping pace with advancements in software delivery processes and tooling is taxing even for the most proficient organizations. Point tools, platforms, open source and the increasing adoption of private and public cloud services requires strong engineering rigor – all in the face of developer demands to use the tools of choice.

There's a lot of things we do to improve the performance of web and mobile applications. We use caching. We use compression. We offload security (SSL and TLS) to a proxy with greater compute capacity. We apply image optimization and minification to content. We do all that because performance is king. Failure to perform can be, for many businesses, equivalent to an outage with increased abandonment rates and angry customers taking to the Internet to express their extreme displeasure.

Right off the bat, Newman advises that we should "think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development". These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that microservices is a set of process techniques as opposed to an architectural approach. Yet in the book, Newman clearly includes some elements of concept model and architecture as well as p...
