From ESBs to API Portals, an Evolutionary Journey | Part 1

The state of the art today is epitomized by cloud computing under the service paradigm

A number of analysts are beginning to suggest 2013 will likely signal the awakening of a long night in the IT industry that started with the beginning of the third millennium with the Internet crash. And just as recovery was around the corner, the financial crisis of 2008 dried the IT well once more. Both crises can be characterized as crises of demand. Just past 2000, the Y2K pipeline ran dry. Some argue that the problem was overstated, whereas others argue that the problem was solved just in time. In either case this event triggered a significant pullback in IT spending.

Faced with an existential threat after Y2K, the IT industry did not sit still. The main outcome from these lean years has been a significant increase in efficiency where the role of IT in companies with most advanced practices shifted from being a cost center to an active participant in the execution of corporate business strategy. Capabilities evolved from no accountability on resource utilization to efficient use of capital to nimble participant in a broad range of organizations and initiatives.  The second crisis reaffirmed the continuing need to do more in the face of shrinking budgets and very likely provided the impetus for the widespread adoption of cloud technology.

The state of the art today is epitomized by cloud computing under the service paradigm. From a historical perspective the current state of development for services is in its third iteration.

The early attempts came in various forms from different angles and as many vendors. The most prominent examples of this era came from application server and connectivity ISVs (independent software vendors) and from operating system vendors: Microsoft, IBM, TIBCO and various Unix vendors of that era. The main characteristic of this era that went roughly from 1995 to 2005 was single-vendor frameworks with vendors attempting to build ecosystems around their particular framework. This approach did not take off, partly because concerns in IT organizations about vendor lock-in and because the licensing costs for these solutions were quite high.

The second era was the era of SOA that lasted roughly from 2000 to 2010. The focus was to re-architect legacy IT applications from silo implementations to collections of service components working together. Most of the service components were internally sourced, resulting perhaps from the breaking former monoliths, and combined with a few non-core third party services. Vendors evolved their offerings so they would work well in this new environment. The technology transformation costs were still significant as well as the demand on practitioners’ skills.  Transformation projects required a serious corporate commitment in terms of deferrals to accommodate process reenginering, licensing fees and consulting costs. As a result, the benefits of SOA were available only to large companies. Small and medium businesses (SMBs) and individual consumers were left out of the equation.

Cloud technology drives the current incarnation for IT services following the crisis of 2008. Clouds notwithstanding, if we look at the physical infrastructure for data centers, it is not radically different from what it was five years ago, and there are plenty of data centers five years ago or older still in operation. However, the way these assets are organized and deployed is changing. Much in the same way credit or other people’s money drives advanced economies, with the cloud other people’s systems are driving the new IT economy.

Scaling a business often involves OPM (other people’s money), through partnerships or issuing of stock through IPOs (initial public offerings). These relationships are carried out within a legal framework that took hundreds of years to develop.

In the real world, scaling a computing system follows a similar approach, in the form of resource outsourcing, such as using other people’s systems or OPS. The use of OPS has a strong economic incentive: it does not make sense to spend millions of dollars in a large system for occasional use only.

Large scale projects, for instance a marketing campaign that requires significant amounts of computing power are peaky in the usage of infrastructure assets, usually start with small trial or development runs, with large runs far and few between. A large system that lies idle during development would be a waste of capital.

Infrastructure sharing across a pool of users increases the duty cycle of infrastructure assets through the sharing of these assets with multiple users.  Cloud service providers define the sandbox whereby a number of corporate or individual users have access to this infrastructure. Cloud computing increases the efficiency of capital use through resource pooling delivered through a service model.

The first step in the infrastructure transformation came in the form of server consolidation and virtualization technology. After consolidation became a mainstream IT practice, the trend has been toward the support of more dynamic behaviors. IaaS allows the sharing of physical assets not just within the corporate walls, but across multiple corporate customers. A cloud service provider takes a data center, namely $200 million asset and rents individual servers or virtual machines running inside them by the hour, much in the same way a jet leasing companies takes a $200 million asset, namely an airliner and leases it to an air carrier which otherwise would not be able to come up with the upfront capital expense. The air carrier turns around and sells seats to individual passengers, which is essentially renting a seat for the duration of one flight.

In other words, the evolution we are observing in the delivery of IT services is no different than the evolution that took place in other, more mature industries. The processes that we are observing with cloud computing and associated service delivery model is no different than the evolution of the transportation industry, to give one example.

As we will see in the next few articles, the changes brought by the cloud are actually less about technology and more about the democratization of the technology: the quantum for delivery used to be so large that only the largest companies could afford IT. Over the past few years IT became accessible to small and medium businesses and even individual consumers and developers: businesses can purchase email accounts by the mailbox with a monthly fee, and deployment models allow individual consumers to sign up for email accounts at no out of pocket cost. We will look at the evolution of the service model from a corporate privilege to mass availability. From a practical, execution perspective, products like the Intel® Expressway Service Gateway and Intel® API Manager were developed to support the life cycle of cloud enabled applications, and I’ll be pointing to aspects of these products to provide specific examples of the concepts discussed.

In the next article we’ll discuss the “big guns” services represented by the SOA movement in the first decade of the millennium.

Hardware will never be more valuable than on the day it hits your loading dock. Each day new servers are not deployed to production the business is losing money. While Moore’s Law is typically cited to explain the exponential density growth of chips, a critical consequence of this is rapid depreciation of servers. The hardware for clustered systems (e.g., Hadoop, OpenStack) tends to be significant capital expenses. In his session at 15th Cloud Expo, Mason Katz, CTO and co-founder of StackIQ, to discuss how infrastructure teams should be aware of the capitalization and depreciation model of these expenses to fully understand when and where automation is critical.
Over the last few years the healthcare ecosystem has revolved around innovations in Electronic Health Record (HER) based systems. This evolution has helped us achieve much desired interoperability. Now the focus is shifting to other equally important aspects – scalability and performance. While applying cloud computing environments to the EHR systems, a special consideration needs to be given to the cloud enablement of Veterans Health Information Systems and Technology Architecture (VistA), i.e., the largest single medical system in the United States.

Most of today’s hardware manufacturers are building servers with at least one SATA Port, but not every systems engineer utilizes them. This is considered a loss in the game of maximizing potential storage space in a fixed unit. The SATADOM Series was created by Innodisk as a high-performance, small form factor boot drive with low power consumption to be plugged into the unused SATA port on your server board as an alternative to hard drive or USB boot-up. Built for 1U systems, this powerful device is smaller than a one dollar coin, and frees up otherwise dead space on your motherboard. To meet the requirements of tomorrow’s cloud hardware, Innodisk invested internal R&D resources to develop our SATA III series of products. The SATA III SATADOM boasts 500/180MBs R/W Speeds respectively, or double R/W Speed of SATA II products.

Enterprises require the performance, agility and on-demand access of the public cloud, and the management, security and compatibility of the private cloud. The solution? In his session at 15th Cloud Expo, Simone Brunozzi, VP and Chief Technologist(global role) for VMware, will explore how to unlock the power of the hybrid cloud and the steps to get there. He'll discuss the challenges that conventional approaches to both public and private cloud computing, and outline the tough decisions that must be made to accelerate the journey to the hybrid cloud. As part of the transition, an Infrastructure-as-a-Service model will enable enterprise IT to build services beyond their data center while owning what gets moved, when to move it, and for how long. IT can then move forward on what matters most to the organization that it supports – availability, agility and efficiency.
Every healthy ecosystem is diverse. This is especially true in cloud ecosystems, where portability and interoperability are more important than old enterprise models of proprietary ownership. In his session at 15th Cloud Expo, Mark Baker, Server Product Manager at Canonical/Ubuntu, will discuss how single vendors used to take the lead in creating and delivering technology, but in a cloud economy, where users want tools of their preference, when and where they need them, it makes no sense.
