Whether you work for a very large company with thousands of services in production or a small company with only a couple, visibility into the performance and uptime of those services is critical. Before you start investigating the myriad of governance products on the market, many of which will set you back a great deal of money, let me save you some time (and money). You can get up and running in about an hour for chump change with JaxView from Managed Methods and get a firm handle on how your services are performing (or not performing as the case may be). If you’ve ever worked with SiteScope for website monitoring, you’ll recognize the quick time-to-value paradigm of JaxView and for good reason – it is brought to you by some of the same people who built SiteScope. You’re going to love JaxView’s intuitive user interface and different deployment options, including an agentless option, which will get you started in a flash. Here’s what you can expect from JaxView for your modest time and money investment:
- Excellent visibility into client-service interactions
- Monitoring service quality, performance, and usage
- Heartbeat monitoring of services a la SiteScope
- Web services security policy administration and enforcement
- Enforcing automated governance policies in runtime
- Mediation and routing
- Integration with UDDI registries, ESBs, directory services, and databases
- An agentless deployment that is easy to get up and running and manage
- An appliance option that you can truly just plug in to evaluate
JaxView requires Windows (XP Pro, 2000 Pro, or 2000 Server), Linux, or Mac OS X. A database is not necessarily required as the file system is used by default to persist monitoring data for 30 days. In case you are monitoring high-volume services, or you need to persist data for more than 30 days or use JaxView’s clustering option, a database is required. Supported databases are MySQL, SQL Server, Oracle, and DB2. On Windows the JaxView server installs as a service and is immediately ready to use as a service proxy gateway. JaxView also has deployment models including an agent-based network sniffer and an ESB connection via JMS. In each of these cases, the central JaxView server receives and persists monitoring data. The management console is hosted on the same server and, once you log in, you see the interface depicted in Figure 1. Web services under management appears in the left pane and can be grouped into folders for convenience. The main frame of the “Services” tab gives you a simple view of the performance and operability (errors, alerts, and faults) for the level of the web services hierarchy (all, folder, or individual service) view that you choose in the left navigation pane. Figure 2 is a summary report of how a service operation is performing. The left nav view is similar to an organizational hierarchy view that would be found in a service registry/repository and, in fact, JaxView has deep and wide integration with UDDI registries – it will gather service and policy metadata from the registry via the UDDI inquiry API as well as update service metadata via the UDDI publication API. Endpoint proxy URLs are automatically published to the service registry once you manage them with the JaxView service gateway, which causes your service consumers to begin using the managed endpoint URL.
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...

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...

With so much going on in this space you could be forgiven for thinking you were always working with yesterday’s technologies. So much change, so quickly. What do you do if you have to build a solution from the ground up that is expected to live in the field for at least 5-10 years? This is the challenge we faced when we looked to refresh our existing 10-year-old custom hardware stack to measure the fullness of trash cans and compactors.

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.

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...

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...

Thomas Bitman of Gartner wrote a blog post last year about why OpenStack projects fail. In that article, he outlined three particular metrics which together cause 60% of OpenStack projects to fall short of expectations: Wrong people (31% of failures): a successful cloud needs commitment both from the operations team as well as from "anchor" tenants. Wrong processes (19% of failures): a successful cloud automates across silos in the software development lifecycle, not just within silos.

[session] Architecting for the Cloud By @RagsS | @CloudExpo @IBMBluemix #Cloud #Docker #Microservices
As the world moves toward more DevOps and Microservices, application deployment to the cloud ought to become a lot simpler. The Microservices architecture, which is the basis of many new age distributed systems such as OpenStack, NetFlix and so on, is at the heart of Cloud Foundry - a complete developer-oriented Platform as a Service (PaaS) that is IaaS agnostic and supports vCloud, OpenStack and AWS. Serverless computing is revolutionizing computing. In his session at 19th Cloud Expo, Raghav...

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...

The following fictional case study is a composite of actual horror stories I’ve heard over the years. Unfortunately, this scenario often occurs when in-house integration teams take on the complexities of DevOps and ALM integration with an enterprise service bus (ESB) or custom integration. It is written from the perspective of an enterprise architect tasked with leading an organization’s effort to adopt Agile to become more competitive. The company has turned to Scaled Agile Framework (SAFe) as ...
