My ramblings about all things technical

VCAP6-CMA Design Objective 2.4 – Build Manageability Requirements into the Logical Design

Leave a comment

Knowledge

Evaluate which management services can be used with a given vRealize Automation Solution.

Management of vRealize Automation is achieved via various methods and solutions. You have management of the underlying vSphere infrastructure via the vSphere client and web client, management and monitoring of both vSphere and vRA via vRealize Operations with management packs for vRA, logging via vRealize LogInsight, change management via third part CMDB tools as well as VMware tools such as vRealize Configuration Manager and Hyperic.

There is also the standard vRA management via the vRA portal and the VAMI portals for management of the vRealize Appliances. I haven’t done the exam but based on previous exam experience I would make sure you know what tabs and options there are for all the vRA VAMI portals.

Differentiate infrastructure qualities related to management.

I partly covered this in the previous 2.3 posting, what they are likely to do from previous experience ( I have not done the exam nor the beta) is to give you a whole bunch of infrastructure qualities and you have to match them up. Manageability is all about ease of management and having the most optimal amount of manageability without impacting other infrastructure qualities or any of the requirements.

Build interfaces into the logical design for existing operations practices.

My take on what they are looking for here is that the customer you are doing the design for has existing operations practices and solutions and you need to take these into account and then design the solution to meet these. So for example if the customer has a CMDB and every time a machine is requested, built, edited and destroyed CI’s need to be passed to the CMDB to track these changes. Another example is syslogging and setting up syslog’s to go to a customer existing logging solution. Reading through the reference architecture and getting an understanding of what kinds of external solutions and services you might need to plug in to is great prep for this. Also adding the vRA management to AD,NTP,SNMP and DNS is very applicable and is required for all deployments (maybe not SNMP for every one)

Address operational readiness deficiencies.

This is where either the customers IT team who are going to look after the solution when you leave aren’t skilled up enough or they don’t have anyone to manage it at all (I’ve seen both in my experience). To fix this knowledge transfer workshops are required, or to link to the manageability infrastructure quality you simplify management as much as possible and try use their existing management mechanisms if they fit so allow easier management of the solution building on existing knowledge. You can also put it as a constraint the lack of existing knowledge to manage the solution and the risk mitigation is training of the team via formal training or learning from yourself and/or the person deploying the solution. You should also read the recommended Operational Readiness Assessment document from VMware.

Define Event, Incident and Problem Management practices.

These are where the logging of the solution and the management of the solution by tools such as vROps, LogInsight, vSphere alarms and event management via 3rd party tools such as Arcsight. The use of LogInsight and vROps is a great combination as they integrate brilliantly together and with the use of the management packs for vRA and LogInsight give amazing manageability of events, incident and problems with intelligent alarms. These can also be tracked by tools such as Service Now which is a fairly popular option for large enterprises in my experience and VMware have even written blogs about the integration http://blogs.vmware.com/management/2015/01/integrating-vrealize-automation-servicenow.html

Design a log management solution.

As mentioned above log management can be done via VMware solutions or 3rd part solutions. LogInsight is most likely the one they are going to reference in the exam seeing as it is VMware’s solution and you can get a vRA management pack for it to allow it to alert on vRA specific alerts https://solutionexchange.vmware.com/store/products/vra-6-1-log-insight-content-pack .

Determine request fulfilment and release management processes.

Request fulfilment I am taking as the fulfilment of all the required parameters to provision as service from the vRA catalogue. You would do this via the service design that you have done for each service where you have defined what parameters need to be fed in and that incorrect values aren’t inserted to ensure service requests are successful. In regards to ASD this is where you make sure the request form is using optimal selection boxes to make sure letters aren’t used where only number should be inserted and drop down lists are used so that only applicable options can be selected.

Release management would also be done in the service design document although it might be the same across all the service offerings or might differ per service offering based on the lifecycles. This would be the definition of when new blueprints are published, where they are published, who they are published to and version control.

Define change management processes based on business requirements.

Change management can be done via logging to ensure if any changes are made they are tracked, this can also be done via the Service Now method I mentioned earlier as well as change management via vRealize Configuration Manager. During design workshops you should ascertain what change management processes they need to follow and then make sure those are met via usage of API’s to the CMDB solution or logging to LogInsight or Arcsight for example.

Based on customer requirements, identify required reporting assets and processes.

Very much like above the customer will define what kind of reporting they are looking for or what you think they should be getting and then producing these reports via tools such as vROps or LogInsight. For the exam I think they are going to have certain reporting requirements given to you such as the Infrastructure manager wants to get a daily report around any alerts that were found in vRA for the past day or sent an email if an alarm is triggered in vRA.

If you think I have something wrong then please let me know as I don’t claim to know everything by any stretch.
