In Part 1 and Part 2 of this series, we created three inputs for our vRealize Automation blueprint: Production, WordPress, SOX compliance. These three inputs correspond to property groups that allow us to associate multiple custom properties to a single input. Using property groups allows us the ability to templatize how each input affects the outcome of a request. In this article, the Genie that we’ve previously released from the proverbial bottle is about to take form, as we walk through how these three inputs come together to determine the outcome of our request.
Let’s look at how the different input options impact the different modules.
In Part 1 of this series we walked through how you can use the SovLabs Property Toolkit and Template Engine to configure vRealize Automation (vRA) for our environment input. In this second part of the series, we’re going to walk through setting up the Application and Compliance inputs for our particular use case. If you are starting to see smoke, don’t be alarmed. It’s just our Genie being let out of the lamp.
In Part 1, we determined that the required options for our Application input will be:
Determine the Outcome
In this scenario, the selection of the application will have a significant impact on the outcome. However, while we need to think about the application, we also need to look at the larger picture. What do I mean by “the bigger picture”? Well, once we figure out the desired outcome for each of these items, we need to think about how each item relates to the environment and the choices we made in Part 1.
What if the requester chooses WordPress as the application and Production as the environment? Alternatively, what if they choose Microsoft SQL and Development? Will the outcome of the application differ based on the environment to which it is being deployed?
Some things to consider:
Do the workload specs change based on the environment selection?
Do development, test, and production instances have the same CPU and Memory requirements?
Do any of the integrations change based on application and environment?
Do WordPress and Microsoft SQL have the same backup requirements?
Does this requirement change based on which environment the workload is being deployed to?
Ever wish you were able to set more than one value from a single vRealize Automation (vRA) request input? Have you ever wished you could make some aspects of vRA more dynamic and flexible? Wish you could simplify the vRA request form? In this article I’m going to let the genie out of the bottle. All your wishes are about to come true. But before we summon our genie, let’s first dive into what it is that we are going to be wishing for. My wish is to have a simple vRA request page with only three inputs that can drive the outcome of every aspect of my request. Sounds too good to be true doesn’t it? We will find out soon enough.
Determine the needed Inputs
Determining what our inputs are going to be. For my scenario I need to the following three inputs:
The Environment (Production, Development, or Test)
The Application (WordPress or Microsoft SQL)
Compliance Needs (SOX or Non-SOX)
In my example, these are the only three items I need to know from the requester to build a server in my environment. The remaining info I can gather from the business group they belong to, what resources the workload is placed on, etc. I know every environment is different and many will require more than three inputs. Once you have read this entire 3-Part series, you will realize the number of inputs doesn’t matter. It’s how we use them that’s key.
Determine the outcome
What outcomes do we need to drive based on these inputs? Or, how will these help determine the outcome of the overall deployment? Will they influence items such as the machine hostname, Active Directory OU placement, vCenter Folder placement, vSphere tagging, application installation, etc?
About the Free Custom Hostname Extension for vRealize Automation
Here at SovLabs we are always helping our audience make the decision to either “build” or “buy”, when it comes to VMware automation solutions. Recently, we have been involved in some discussions about the free Infoblox plugin for vRealize Automation. Specifically,these discussions are around how the free Infoblox plugin for vRealize Automation handles custom host naming. That discussion prompted us to consider all such customizations and the support required when when they are integrated with vRealize Automation.
Custom Automation Considerations
There are a few issues at play here, including:
How do the different components of your solution work together?
Was it designed wholistically or were pieces added on as you needed them?
Did one source develop all of the components, or are they pulled piecemeal from multiple places?
If one source did all of the development – are they still available?
Who is supporting the development work going forward?
My six-year-old asked me to tell him a bedtime story and it went something like this.
Jimmy and Tommy are both vRA admins. Jimmy works for a large financial company and Tommy works for a large company that makes really cool stuff. Both Jimmy and Tommy made great decisions to use vRA to automate their private clouds. Jimmy decided his organization was going to build all their own integrations. Tommy decided to use the SovLabs plugin for all his organizations needs.
Four weeks after Tommy’s vRA deployment his company was using vRA to deploy 75% of their virtual deployments. Meanwhile after four weeks Jimmy is just getting started designing the first of many needed integrations. Fast forward a year and Tommy’s organization is now deploying 100% of their workloads. They have reduced management overhead by 45%, and are able to deploy new server requests in under an hour.
A year later Jimmy’s company is still working out bugs with their custom code. Their administrative overhead is up 55% and it still takes over two-weeks for new server requests to be fulfilled. Jimmy is working 80+ hours a week and perpetually stressed. Tommy on the other hand is working 30 hours a week, but don’t tell his boss. He is enjoying his job and has next to no stress.
I then ask my six-year-old who he would rather be Jimmy or Tommy? He responded neither daddy I would rather be you. I asked him why he said he wanted to be me. He responded, because daddy you helped Tommy only have to work 30 hours a week.
GSS has decided on a number of design considerations for their vRA implementation. GSS is currently using a consumption based model for their resource allocation. They don’t pre-reserve any amount of resources for specific groups within the organization. GSS feels their current consumption model allows them to more efficiently manage their resources. It also prevents them from having pockets of idol resources that may never get used. Based on this utilization model GSS will be implementing the following elements within vRA.
GSS considered having a business group for each environment (Dev, Test, Stage, and Production). To evaluate how they would like to proceed they asked to have 5 initial tenants created. One for each of their environments and one to evaluate a collapsed model of all environments in one group.
Development – All Developers across all groups within GSS
I think we need to take a few steps back and focus on vRA architecture and design. I’ve had many questions, requests, and discussions with some of my readers on this topic. Implementing vRA can lead to many rewarding outcomes, but as some have discovered it can also lead to aggravating outcomes if not designed properly upfront.
At first it can seem very straight forward. Create some endpoints, groups, reservations, and blueprints. Sprinkle in some integrations for custom hostname, IPAM, DNS and AD and you are on your way to fully automating your workload deployments, right? Not exactly. You can certainly do this and at first it will seem amazing, but as you mature and start to scale out your new catalog of services the lack of up front design and planning will quickly start to reveal itself.
Many of you may have already heard after 6 years at VMware I decided to spread my wings and go back to the world from which I came. I joined VMware when they acquired DynamicOps a little over 6 years ago, and after 6 great years at VMware I decided to move on to something new, but not so new.
If it doesn’t show from my blog I am very passionate about automation. I’m even more passionate about helping organizations overcome all the challenges they face during their journey towards automation. Having been working with vRA for over 10 years I’ve learned a lot. I’ve learned the countless ways different organizations go about achieving the same end result. I’ve learned the challenges with automation in the datacenter. I’ve learned I could probably write endlessly about what I have learned
Many of you may have heard about Amazon’s latest product named Lightsail. This service is designed to competed with shared hosting providers. A few years back I moved my websites from shared hosting, to self hosing, and ultimately to a dedicated server with 1&1 hostsing. For $85 a month it wasn’t a bad deal. Although the server seemed very sluggish at times and the network wasn’t very fast it was still better than shared hosting.
Over the course of the last two weeks I moved all my web assets to Amazon Lightsail and I couldn’t be happier. The Amazon network is lightening fast and the $5 per month instance is out performing the dedicated server I had from 1&1 hosting. Lightsail offers many plans starting at $5 a month all the way to $80 a month.
Many of you have utilized the Custom Hostname module that has been made available by Tom Bonanno here on Dailyhypervisor. Those that use have probably noticed that it is no longer maintained. This is because there are supportable modules available like the one I’m writing about now by SovLabs. The Sovlabs module offers more flexibility and is a supported product making it a best of breed solution for this task. Whats even better is their is a common framework that exists within the SovLabs platform that greatly extends the capabilities of each module. More of the framework to come. For now let’s go ahead and configure the custom hostname module.
Within the SovLabs custom naming module hostnames are broken in to two parts. A Naming Sequence and a Naming Standard.
Naming sequences are exactly exactly what they sound like. They basically define how are we going to sequence the names that are created. Sounds basic right? Well SovLabs has taken sequencing to a whole new level. Most of you are probably familiar with using a standard decimal based sequence that might look like host001, host002, and so on. SovLabs has added the ability to use HexaDecimal, Octal, and Pattern based sequences for your naming needs. Pattern based sequences are insanely powerful. Pattern naming sequences can contain Decimal, HexaDecimal, Octal, Binary, and Alpha. Below are an examples of what you can achieve with Pattern Based naming sequences: Continue reading “vRA 7.3 – Configuring SovLabs Custom Naming Module”
