Focusing your service-oriented architecture (SOA) performance management efforts on the application testing stage or attempting to manage production SOA applications solely with traditional point solutions and network management tools is a recipe for disaster, putting your customer's satisfaction and your company reputation on the line. Production SOA Performance and Service Level Agreement (SLA) management must be built into the overall SOA strategy.
Service-oriented architecture and virtualization are hot topics in almost every publication, blog, website, and IT strategy meeting today. The reality is that both of these technologies have been around for some time but are finally achieving broad market adoption and playing a key role in improving efficiency and lowering development and operational costs, and contributing to higher service levels, increased customer satisfaction, and contributing to bottom line results.
Since the beginning of the Information Technology (IT) era, newer and more innovative solutions have emerged at a phenomenal rate but most organizations are taking a phased or evolutionary approach and testing the water before widespread adoption. A recent survey of over 600 large enterprise organizations either already invested in, or seriously considering SOA, in North America, Europe, and the Pacific confirms that SOA is in fact becoming more mainstream and adoption is accelerating (see Figure 1).
This article for the most part skips the "Why SOA." The generally accepted and most frequently mentioned reasons for considering SOA include the notion of faster and more cost-effective application development based on the assumption that once a particular service is defined, it can be reused by a number of business processes versus re-inventing that particular service for every business process with a similar need. This also lends itself to enforcing some standards within an enterprise by always delivering or performing a particular service the same way. Faster application development and deployment can help make organizations more agile to introduce new business process functionality in response to user needs and market or product dynamics.
Chances are, if you are reading this article, you already recognize the advantages of SOA, and have already deployed a SOA application or you are seriously considering deploying SOA and need to look more closely at SOA Application Performance Management (APM).
Govern, Manage, and Secure
One characteristic SOA shares with many new technologies is that while it simplifies the visible, user-facing process or service, it typically adds significant complexity to the underlying infrastructure. APM can be viewed as one of the three legs of the SOA infrastructure management stool. The other two are security management and governance. All three are important to managing the SOA infrastructure to provide a high performance, secure, and structured SOA environment.
Application transformation and DevOps practices are two sides of the same coin. Enterprises that want to capture value faster, need to deliver value faster – time value of money principle. To do that enterprises need to build cloud-native apps as microservices by empowering teams to build, ship, and run in production. In his session at @DevOpsSummit at 19th Cloud Expo, Neil Gehani, senior product manager at HPE, discussed what every business should plan for how to structure their teams to delive...

Without lifecycle traceability and visibility across the tool chain, stakeholders from Planning-to-Ops have limited insight and answers to who, what, when, why and how across the DevOps lifecycle. This impacts the ability to deliver high quality software at the needed velocity to drive positive business outcomes. In his general session at @DevOpsSummit at 19th Cloud Expo, Phil Hombledal, Solution Architect at CollabNet, discussed how customers are able to achieve a level of transparency that e...

IT leaders face a monumental challenge. They must figure out how to sort through the cacophony of new technologies, buzzwords, and industry hype to find the right digital path forward for their organizations. And they simply cannot afford to fail. Those organizations that are fastest to the right digital path will be the ones that win. The path forward, however, is strewn with the legacy of decisions made long ago — often before any of the current leadership team assumed their roles. While it’s ...

Kubernetes is a new and revolutionary open-sourced system for managing containers across multiple hosts in a cluster. Ansible is a simple IT automation tool for just about any requirement for reproducible environments. In his session at @DevOpsSummit at 18th Cloud Expo, Patrick Galbraith, a principal engineer at HPE, discussed how to build a fully functional Kubernetes cluster on a number of virtual machines or bare-metal hosts. Also included will be a brief demonstration of running a Galera MyS...

As we enter the final week before the 19th International Cloud Expo | @ThingsExpo in Santa Clara, CA, it's time for me to reflect on six big topics that will be important during the show. Hybrid Cloud: This general-purpose term seems to provide a comfort zone for many enterprise IT managers. It sounds reassuring to be able to work with one of the major public-cloud providers like AWS or Microsoft Azure while still maintaining an on-site presence.

Between 2005 and 2020, data volumes will grow by a factor of 300 – enough data to stack CDs from the earth to the moon 162 times. This has come to be known as the ‘big data’ phenomenon. Unfortunately, traditional approaches to handling, storing and analyzing data aren’t adequate at this scale: they’re too costly, slow and physically cumbersome to keep up. Fortunately, in response a new breed of technology has emerged that is cheaper, faster and more scalable. Yet, in meeting these new needs they...

Logs are continuous digital records of events generated by all components of your software stack – and they’re everywhere – your networks, servers, applications, containers and cloud infrastructure just to name a few. The data logs provide are like an X-ray for your IT infrastructure. Without logs, this lack of visibility creates operational challenges for managing modern applications that drive today’s digital businesses.

Today we can collect lots and lots of performance data. We build beautiful dashboards and even have fancy query languages to access and transform the data. Still performance data is a secret language only a couple of people understand. The more business becomes digital the more stakeholders are interested in this data including how it relates to business. Some of these people have never used a monitoring tool before. They have a question on their mind like “How is my application doing” but no id...

In IT, we sometimes coin terms for things before we know exactly what they are and how they’ll be used. The resulting terms may capture a common set of aspirations and goals – as “cloud” did broadly for on-demand, self-service, and flexible computing. But such a term can also lump together diverse and even competing practices, technologies, and priorities to the point where important distinctions are glossed over and lost.

Monitoring of Docker environments is challenging. Why? Because each container typically runs a single process, has its own environment, utilizes virtual networks, or has various methods of managing storage. Traditional monitoring solutions take metrics from each server and applications they run. These servers and applications running on them are typically very static, with very long uptimes. Docker deployments are different: a set of containers may run many applications, all sharing the resource...
