Deploying APM in the Enterprise. In the last installment we covered how you find, test, and justify purchasing an APM solution. This blog will focus on what to do after you’ve made a purchase and started down the path of deploying your coveted APM tool (ahem, ahem, AppDynamics, ahem). Just clearing my throat, let’s jump right in…
Welcome to Part 4 of my series It’s time for a celebration, time to break out the champagne, time to spike the football and do your end zone dance (easy there Michael Jackson, don’t hurt yourself). All of the hours you spent turning data into meaningful information, dealing with software vendors, writing requirements, testing solutions, documenting your findings, writing business justifications, and generally bending over backwards to ensure that no objection would stand in your way has culminated in management approving your purchase of APM software. Now the real work begins…
The 7 Ps
This blog post is a great general outline for planning your implementation. Everything covered in this post should be part of your planning process and should be considered the bare minimum for APM deployment planning within your organization.
Controller: The Brain, Narf!
The first major decision will be an easy one. You probably already covered this during the evaluation, vendor selection, and negotiation phases but we will recap here. You need to decide if you will host your own controller or use the vendors SaaS environment. In case you don’t already know, a controller is the server component that collects, stores, analyzes, etc… the monitoring data from the agents. Basically the controller is the brains behind the operation. There are many factors that you need to consider when deciding to use a SaaS or On-Premise model and we will not cover them in this post. Your vendor of choice (ahem, ahem, AppDynamics, ahem) will help you decide which option is right for your business circumstances.
So you’ve decided to host your own controller(s). We have many clients that choose this route for one reason or another and we make every effort to support you just as well as using the SaaS option. In this case we wont be doing all of the work for you so you need to get cracking on your server deployment process. I hope it’s super easy and streamlined and you can have a new host set up and ready to load software in an hour or less. In reality it may take you a few weeks or even months so you need to be familiar with the lead time so that you can appropriately plan the rest of the deployment. You NEED a controller so there is no point in deploying agents without one. Use this lead time to generate the most awesome plan ever!
Agents: Deploying and Configuring
Deploying APM agents should be easy. Add a very small amount of software to the server you want to monitor, reference the agent software in your application configuration and restart your application. It’s basically that easy to deploy an agent. It should also be really easy to configure. In fact, the agent should automatically detect what it needs to monitor and simply just work. This is how AppDynamics works but the same does not hold true for most other APM vendors. Hopefully you saw this when you ran each vendor solution through your POC environment. In the interest of full disclosure I will admit that there are circumstances where NO APM solution can automatically detect your application properly and there is more configuration work to do. This is a problem that every APM vendor has to deal with but thankfully AppDynamics sees this condition with only a very small subset of its customer base. Usually you plug in our agent and we show you what you need to see. It just works!
Awesome, now that we just saved you 80% of the configuration time versus deploying “the other guys” what’s next?
If things don’t look right you need to figure out why. It might be that your application really is different than you thought (we see this quite often), or it could be a problem with the monitoring. Resolve any issues you see before declaring deployment and configuration victory.
Production Load Cannot Be Simulated Exactly!!!
Beyond the technology aspects of running in production you also need to consider your existing processes. Your shiny new APM tool will provide incredible insight into application issues as long as you have it integrated into your processes. Here are some points to consider:
What I am trying to say is; Give your company every opportunity to use the hell out of your new tool!
Teach Them Well
These short presentations will equip you with the information you need to defend your decision to purchase APM, justify a larger investment, and propel yourself to rockstar status within your organization.
There is a lot of work that needs to be done to successfully deploy, configure and use an APM tool in the enterprise but the potential rewards are staggering. Think about how much lost revenue can be avoided by ensuring your revenue generating applications don’t go down at peak times. People notice when the decisions you make and the work you do directly impact the bottom line. Put in the effort and get noticed!
