What Customers expect in a new generation APM (2.0) solution

In the last blog, I discussed the challenges with an APM 1.0 solution. 

 

As an application owner or application support personnel, you want to

  • Exceed service levels and avoid costly, reputation-damaging application failures through improved visibility into the end-user experience
  • Ensure reliable, high-performing applications by detecting problems faster and prioritizing issues based on service levels and impacted users
  • Improve time to market with new applications, features, and technologies, such as virtualization, acceleration, and cloud-based services

 

The APM 2.0 products enable you manage application performance leading with real user activity monitoring. Following are some of the top functionalities they provide that help you achieve your business objectives.

Visibility to real users and end-user driven diagnostics

  • APM 2.0 solutions provide visibility to end-to-end application performance as experience by real end users and help application support to focus on critical issues affecting end-users.

 

The dashboard shown in Figure 1, as an example, provides visibility of application performance as experienced by users in real-time.

  • As an application owner, you probably care about which users are impacted, what pages they are navigating and what kind of errors they are getting. You want your APM product to improve MTTR by identifying what is causing the latency issues or failure e.g. network, load balancer, ADN like Akamai, SSL or the application tier itself. Figure 2 shows a specific user session and what pages the user navigated and identified that the application tier is the cause.

  • The “details” link in Figure 2 allows the application support personnel to drill down further which application tier is the culprit for the slow or failed transaction in context to the specific user. This allows the application support personnel to track end-user request to the line of the code.

Ease of use and superior time-to-value

You want to use a product that is simple to use for your application support / operation team.

  • A modern APM solution does not require manual definition of instrumentation policies.
  • It should not require manual changes such as Java script injection for visibility to the end user.
  • APM 2.0 tools provide ability to drill down from end-user to deep-dive for diagnostics and drill up from deep-dive data to identify the impacted user and the context for the transaction without having to do a manual correlation, jumping between consoles.
  • The agent install is typically a 5-10 mts process in the modern APM deep-dive tools.
  • The APM 2.0 deep-dive solution provides automatic detection of application servers, business transactions, frameworks etc.

 

Figure 3 shows a specific user transaction request and latencies by tiers. It also shows the SQL and latencies information.

Suitable for production deployment

  • The real user monitoring tool should be non-invasive in nature and it should put additional overhead on application response time.
  • You should be able to deploy an always-on, deep-dive monitoring and diagnostic solution for your production enterprise and cloud-based applications.
  • It should work in an agile environment without having to configure new instrumentation policies with application releases.
  • It should scale for a large production deployment to 1000s of application servers that you want to manage in your production environment.

 

Operations Ready product and enables DevOps collaboration

The APM 1.0 products were originally built for developers and hence they were not very intuitive for operations use. The APM 2.0 products are operations friendly. Also you would expect some of those to enable DevOps collaboration for intelligent escalation to development.

  • Most application support personnel do not understand what frameworks or application technologies used by an application. The majority deep-dive tools in the market move very fast from a transaction view to line of code thus being not providing much value to operations team.

 

For example, Figure 4 shows the transaction break-down by specific technologies used by the transaction. This also provides baselines for different tiers and the system resource usage along with tiers to make intelligent decision. Figure 3 shows an application flow map for a specific transaction and time spent in each SQL or a remote web service call without having to drill down to the line of code.

  • There are many instances operations team need to escalate problems to developers. The tool should allow application support personnel to escalate to Tier 3/development for diagnostics by sending a direct link to the diagnostic instance. However in many organizations, developers do not have access to production environment and as shown in Figure 5, solution from BMC allows exporting the diagnostics data call tree with latency, parameters, etc in a HTML format.

Adaptive to virtualization and Cloud environment

The new APM 2.0 products are purpose-built and architected for cloud and virtualized environments. 

  • The APM 2.0 product components and agents are designed to communicate in a firewall-friendly protocol and can be encrypted / secured.
  • They support virtualized and dynamic environment without causing a lot of false alerts.
  • They support modern cloud frameworks and Big Data platforms such as Hadoop.

 

Conclusion

The APM 2.0 solution provides the functionalities that you need to manage your applications that will help exceed business expectations and increase customer loyalty. These tools provide capability to improve time to market. These provide you understanding how application performance affects user behavior — and how that behavior impacts the bottom line. You can leverage an APM 2.0 solutionlike BMC Application Performance Management to improve your application performance and thus meeting your business objectives.

The Internet of Things. Cloud. Big Data. Real-Time Analytics. To those who do not quite understand what these phrases mean (and let’s be honest, that’s likely to be a large portion of the world), words like “IoT” and “Big Data” are just buzzwords. The truth is, the Internet of Things encompasses much more than jargon and predictions of connected devices. According to Parker Trewin, Senior Director of Content and Communications of Aria Systems, “IoT is big news because it ups the ante: Reach out ...
"We got started as search consultants. On the services side of the business we have help organizations save time and save money when they hit issues that everyone more or less hits when their data grows," noted Otis Gospodnetić, Founder of Sematext, in this SYS-CON.tv interview at @DevOpsSummit, held June 9-11, 2015, at the Javits Center in New York City.
Auto-scaling environments, micro-service architectures and globally-distributed teams are just three common examples of why organizations today need automation and interoperability more than ever. But is interoperability something we simply start doing, or does it require a reexamination of our processes? And can we really improve our processes without first making interoperability a requirement for how we choose our tools?
At DevOps Summit NY there’s been a whole lot of talk about not just DevOps, but containers, IoT, and microservices. Sessions focused not just on the cultural shift needed to grow at scale with a DevOps approach, but also made sure to include the network ”plumbing” needed to ensure success as applications decompose into the microservice architectures enabling rapid growth and support for the Internet of (Every)Things.
How do you securely enable access to your applications in AWS without exposing any attack surfaces? The answer is usually very complicated because application environments morph over time in response to growing requirements from your employee base, your partners and your customers. In his session at @DevOpsSummit, Haseeb Budhani, CEO and Co-founder of Soha, shared five common approaches that DevOps teams follow to secure access to applications deployed in AWS, Azure, etc., and the friction an...
Digital Transformation is the ultimate goal of cloud computing and related initiatives. The phrase is certainly not a precise one, and as subject to hand-waving and distortion as any high-falutin' terminology in the world of information technology. Yet it is an excellent choice of words to describe what enterprise IT—and by extension, organizations in general—should be working to achieve. Digital Transformation means: handling all the data types being found and created in the organizat...
This week, I joined SOASTA as Senior Vice President of Performance Analytics. Given my background in cloud computing and distributed systems operations — you may have read my blogs on CNET or GigaOm — this may surprise you, but I want to explain why this is the perfect time to take on this opportunity with this team. In fact, that’s probably the best way to break this down. To explain why I’d leave the world of infrastructure and code for the world of data and analytics, let’s explore the timing...
The Software Defined Data Center (SDDC), which enables organizations to seamlessly run in a hybrid cloud model (public + private cloud), is here to stay. IDC estimates that the software-defined networking market will be valued at $3.7 billion by 2016. Security is a key component and benefit of the SDDC, and offers an opportunity to build security 'from the ground up' and weave it into the environment from day one. In his session at 16th Cloud Expo, Reuven Harrison, CTO and Co-Founder of Tufin,...
You often hear the two titles of "DevOps" and "Immutable Infrastructure" used independently. In his session at DevOps Summit, John Willis, Technical Evangelist for Docker, covered the union between the two topics and why this is important. He provided an overview of Immutable Infrastructure then showed how an Immutable Continuous Delivery pipeline can be applied as a best practice for "DevOps." He ended the session with some interesting case study examples.
Discussions about cloud computing are evolving into discussions about enterprise IT in general. As enterprises increasingly migrate toward their own unique clouds, new issues such as the use of containers and microservices emerge to keep things interesting. In this Power Panel at 16th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the state of cloud computing today, and what enterprise IT professionals need to know about how the latest topics and trends affect t...
JavaScript is primarily a client-based dynamic scripting language most commonly used within web browsers as client-side scripts to interact with the user, browser, and communicate asynchronously to servers. If you have been part of any web-based development, odds are you have worked with JavaScript in one form or another. In this article, I'll focus on the aspects of JavaScript that are relevant within the Node.js environment.

Puppet Labs has published their annual State of DevOps report and it is loaded with interesting information as always. Last year’s report brought home the point that DevOps was becoming widely accepted in the enterprise. This year’s report further validates that point and provides us with some interesting insights from surveying a wide variety of companies in different phases of their DevOps journey.
Containers are changing the security landscape for software development and deployment. As with any security solutions, security approaches that work for developers, operations personnel and security professionals is a requirement. In his session at DevOps Summit, Kevin Gilpin, CTO and Co-Founder of Conjur, will discuss various security considerations for container-based infrastructure and related DevOps workflows.
Microservices are hot. And for good reason. To compete in today’s fast-moving application economy, it makes sense to break large, monolithic applications down into discrete functional units. Such an approach makes it easier to update and add functionalities (text-messaging a customer, calculating sales tax for a specific geography, etc.) and get those updates / adds into production fast. In fact, some would argue that microservices are a prerequisite for true continuous delivery. But is it too...

These are the top 5 Summer DevOps Conferences of 2015.
What we really mean to ask is whether microservices architecture is SOA done right. But then, of course, we’d have to figure out what microservices architecture was. And if you think defining SOA is difficult, pinning down microservices architecture is unquestionably frying pan into fire time. Given my years at ZapThink, fighting to help architects understand what Service-Oriented Architecture really was and how to get it right, it’s no surprise that many people ask me this question.
One of the ways to increase scalability of services – and applications – is to go “stateless.” The reasons for this are many, but in general by eliminating the mapping between a single client and a single app or service instance you eliminate the need for resources to manage state in the app (overhead) and improve the distributability (I can make up words if I want) of requests across a pool of instances. The latter occurs because sessions don’t need to hang out and consume resources that could ...
"ProfitBricks was founded in 2010 and we are the painless cloud - and we are also the Infrastructure as a Service 2.0 company," noted Achim Weiss, Chief Executive Officer and Co-Founder of ProfitBricks, in this SYS-CON.tv interview at 16th Cloud Expo, held June 9-11, 2015, at the Javits Center in New York City.
