Cloud computing has essentially been private from the beginning. Google, for one, demonstrates that the world's most successful search engine runs not on an IBM Power, Sun Enterprise, or other massively powerful machine engineered for business by the go-to-vendors for computer solutions. More in keeping with its democratic, spare, and ubiquitous, engineering ethos Google created a "cloud" of white box computer - throw-away hardware servers running Linux.
Rather than purchase software box-software or hire a large consulting firm to design and build the infrastructure, Google engineered proprietary software to enable search requests and indexing tasks to be coordinated across this white "cloud" of white box hardware. Like most innovations that somehow become synonymous with brilliance and innovation, the innovation of using large numbers of identical machines to process enormous amounts of work isn't new at all. In fact it isn't even an innovation that can be attributed to computing at all.
If the cloud's origin is essentially private, what is the "public cloud"? One possible definition is that the public cloud is a disruptive channel through which to package and deliver some of the advantages of the cloud to "the public." Why is the public interested in the cloud? The cloud promises advantages that elude even the largest enterprises today. Public cloud computing services are purchased by individual users, small business, medium-sized business, and one of the world's largest firms.
What problems does the business community imagine the cloud might solve? Traditional technology solutions take a lot of time and money to implement, yet business needs to move quickly and flexibly to seize new opportunities. The business systems of yesterday seldom adapt easily to new requirements. And the work involved in adding new capabilities to existing systems is almost always significantly greater than the effort to build from scratch. Given this dynamic, the risk of building new systems or modifying existing systems seems high. What makes the current practice even less appealing is the tendency over time for the cost of maintaining existing systems to grow. Some studies show that today maintaining current systems consumes seventy percent of a firm's technology budget.
Given these dynamics, the (public) cloud computing model seems to offer an approach that mitigates some of the issues faced in businesses of all sizes.
- Firms would like to be able to purchase focused, low-cost, customizable, and flexible technology services
- Pay for these services when and how they are consumed. For example, some cloud computing vendors offer a metered rate model in which the firm or individual pays for just the right amount and quality of resources required to meet demand.
- Provision these firms as they are needed. If a company needs to provide a temporary call center in Asia for three months while consolidating their data centers in the region, then the cloud computing model offers the ability to provision, configure, and host the software and desktops to do so. If a 25-person firm decides that a customer relationship management solution seems like a good idea, the firm can provision and use that solution in the cloud.
Beyond the rapid deployment, the capability to flexibly alter and shape technology services in the cloud infrastructure can help firms design, deploy, and "shape" technology solutions that fit their immediate needs, yet can adapt over time as the business evolves. In other words, compared to traditional technology practices, the financial model of the cloud seems attractive.
CIOs and business owners tend to look at the return on investment for existing and new technology spending. One of the key factors in the ROI model of investment is the length of time, or "payback" period over which the benefits of the expenditure outweigh the costs. It's not any easy decision because in the traditional model, the CIO purchases equipment, software, services, training up-front, and then hopes that the benefits can be clearly demonstrated. Yet most firms have difficulty tracking costs and benefits in a way that makes the outcome clear. If the CIO chooses too little hardware, or implements a solution that the business users later reject, the whole solution can require additional customization or additional hardware. The cloud computing model assists in mitigating these risks by enabling both the cost and the benefit flows to be aligned. Because the building blocks of a cloud solution are much more scalable, many aspects of the solution can be tuned.
Most firms choose not to write their own desktop operating system or desktop applications. Firms make these choices every day. Yet much of the computing expenditures today deliver little competitive advantage, yet consume scarce and valuable human and capital resources. For a firm like Google, a Private Cloud of white boxes orchestrated to index and return search results makes sense. Yet, for the majority of businesses the public cloud computing model may enable business to better align the cost of computing with the business value, and make competitive advantages achievable through technology.

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...

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...

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...

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, ...

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...

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'...
