vCNS Edge Upgrade Step by Step

As promised, here’s the vCNS Edge upgrade step by step procedure.

Before upgrade vCNS Edge you must upgrade vCNS Manager, if you haven’t done it yet, check the vCNS Manager Upgrade step by step post. That’s required because vCNS Manager holds the binaries to upgrade the others components, as vCNS Edge.

- Open vCNS Manager Admin Page;

- Expand the Datacenters and select the Datacenter where vCNS Edge is deployed at;

- Select Networking Virtualization tab and the from the list of Edges select the one you would like to upgrade;

- Click on the Actions  and select Upgrade;

- Click Yes to proceed with the upgrade.

During the upgrade, there will be a brief network disruption to virtual machines that are using the Edge as their default gateways. The effect is isolated to traffic routed through the Edge Gateway, local traffic between virtual machines in the same subnet will remain unaffected. Also VPN connections will be lost and they will need to be reestablished.

My advice is to perform this action only during periods of low utilization.
Analyze the situation with caution before proceed.

You can also check for more details at vCloud Network and Security Installation and Upgrade Guide or the KB article about the best practices for upgrading vCloud Network and Security.

Easy, easy, easy…

RabbitMQ Essentials Review

Recently I had the opportunity to read the RabbitMQ Essentials book, published by Packt Publishing, and I’d like to share with you my thoughts about this book.

The title of the book let me to believe it was an infrastructure book, which would explain us all the concept and RabbitMQ’s components in a traditional way, like an entirely section dedicated to exchanges and all their settings, other just about queues and so one, but I soon realized it has been written oriented to software architects and engineers.

I decided to give it a change anyway.

The methodology used buy the authors are a kind of role play model. There’s this fictitious company with a need for a new solution and as the chapters evolves the challenges and needs of this company evolves as well.

Like in the real world, the authors are solving immediate needs to fulfill a solution, the solution are very well explained, but they don’t explain further options or another settings that might exist, just because it did not matter for the solution at that time.
But as new needs and challenges pops up, new concepts and setting are getting introduced and explained.

Letting you to learn as you need and not everything at once.

In my opinion, they could cover more about the Admin GUI interface, they don’t mention about how to use it to create exchanges and queues for instances, instead there are codes that show will how to do all of that. It fits perfectly for programing guys that might be looking for it, but not for and infrastructure guys, like me, I like the GUIs : )

The programing guys will love the hundreds of lines of code and examples to implement a messaging solution; it might be that start they need to writte their own solutions.
Ohh, did I mention you can also download all those codes from the website ? Yes, you can.

But what about the Infrastructure guys ? I still think there’s value on it, specially Chapter 7, Taking RabbitMQ to Production, which is all about making RabbitMQ high available with the use of a clustering solution, is not it what all infrastructures guys care about or what ?!?!

There are a lot of digital options available and also a print one, go check it out.

SUSE Linux Enterprise Server (SLES) for VMware End of Availability

If you did not know, when you purchase licenses of VMware vSphere (Standard, Enterprise or Enterprise+) you would be entitled to licenses of SUSE Linux Enterprise (SLES) for VMware.

Well, this offering will be removed on July 25th, 2014, when VMware will be announcing the End of Availability (EOA) of it.

Since it will not be available for purchase anymore, for how long can I still use the product ?
To the ones who acquire it, for as long as you want.

VMware will provide support and fixes for a limited period of time, there will also be a Long Term Service Pack Support, check KB2080129 for all the details.

For a long term solution I advise you all to check the options directly with SUSE.

See you

vCNS Manager Upgrade Step by Step

From time to time, it’s likely that you need to upgrade your products, it might be due a new version or a security fix, like Heartbleed threat.

 Let me show you a step by step procedure on how to upgrade vCNS Manager.

First of all, take a snapshot of your vCNS Manager, so you can revert it in case of an upgrade failure;

- Download the upgrade bundle package;

- Open vCNS Manager Admin Page;
- Click on Settings and Reports and on Updates Tab.

- Click on Upload Upgrade Bundle than browser for the file you just downloaded and click Upload File;

- Click OK to confirm the operation;

- Click Install to proceed with the upgrade;

- Click  Confirm Install;

 At this point the upgrade will be installed and vCNS Manager will be rebooted to conclude the upgrade process.
You can check the progress on the status chart on the upper right corner
Once it’s done, just wait a few minutes and click on the link to login again and check the status of the upgrade process

 Go to the Updates tab to check the current version installed.

After validation that everything is working as expected, dont forget to remove the snapshot.

For more details check the Installation and Upgrade Guide.

Now you need to upgrade the routers and firewalls of your environment, I'm talking about vCNS Edge, here's a procedure that shows how..... coming soon

vCenter Heartbeat End of Availability

 Following Chargeback and vSphere Storage Appliance, it’s now time of vCenter Heartbeat being announced as End of Availability (EOA).

I know I mention it twice already, but it worth to mention again.

End of Availability (EOA) is not End of Life (EOL), which means, when a product is EOA you will not be able to purchase it anymore, for Heartbeat this date was June 2nd, 2014.
Since it’s NOT EOL yet, you can still using the product for as long as you wish, VMware will still provide support and release fix patches until the EOL of the product, which for Heartbeat is September 19th, 2018. (more details you can check at the VMware’s LifeCicle Matrix)

If we think about it for a minute, we will see why VMware is doing that.
That’s my point of view of this situation, let’s see if I can persuade you ; )

- VMware is moving all it’s components toward an appliance oriented solution, since Heartbeat is a Windows base solution it does not fit on this vision;
- As a best practice, vCenter should be installed on a virtual server, in this case High Availability provides enough protection for the majority of business case;
- The complexity of installing and managing Heartbeat does not result in meaningful uptime for the application if compared to High Availability.

Does that mean VMware is not concerned about other options to protect it’s core service ?
Absolutely NOT, I’m sure we will see soon new ways of protecting it.

Stay tuned
