Disaster Recovery – Do you really need one?

 Last week, Microsoft announced the Preview of Capacity Reservation for VMs. You can reserve VM capacity in your DR region to ensure that you have VM resources available to create or turn on your protected VMs using ASR. ASR does not guarantee that your VMs can be turned on in your DR region in the event of disaster recovery. So, capacity reservation is a welcome feature and much needed. However, this is increasing the cost of your solution again.

  • Cost factors
    • VM cost
    • ASR protected VM cost
    • Capacity Reservation Cost ( as same as your actual VM cost)
    • other costs

Note: DR is not just the VMs but including other components. I did not provide the details above because it applies to both the options.

Hmm.. Can we plan a DR cost-effectively in Azure? Let’s take a look:

Review of Preview – Azure Capacity Reservation

The long waiting feature is now Public Preview. When there is a Azure region disaster recovery, we need our VMs to be turned on in the secondary region. This feature guarantees you the recovery. You may learn about this feature in this URL

As you know already, Azure Site Recovery does not 100% guarantee to turn on your VMs in the event of DR. This feature addition helps you gaining more confidence with your BCP with this feature addition. 

  • Take a look at the Microsoft statement about the use cases for this feature. 
    • Business-critical applications—use on-demand capacity reservations to protect your capacity, for example when taking these VMs offline to perform updates.
    • Disaster recovery—you now have the option to set aside compute capacity to ensure a seamless recovery in the event of a natural disaster. The compute capacity can be repurposed to run other workloads whenever DR is not in effect. The VM maintenance can be handled by keeping core images up to date without the need to deploy or maintain VMs outside of DR testing.
    • Special events—claiming capacity ahead of time provides assurance that your business can handle the extra demand.

I have been asking for this feature for a long time now, and finally, it is here. I am happy about Microsoft as they are listening to customers and partners. However, the first bullet point is a bit worrisome as it states, It is not guaranteed to get your VM back if it is offline for some time due to maintenance. Does MSFT force customers to take this for all the critical workload? I hope they do not make things worse to this point.

Cultivate a fearless culture in the organization

Every failure is lot of learning and learning is key for the success.  Question is can we not learn without the failure, may be. But failure is not bad if you don’t stop there.

You have seen this subject already in many articles on this I do not want to talk about it but I would like to talk about building a culture in the organization to encourage people to take risks without fear of failure which result in loosing your job . Leadership in the organization should be able bring the innovation to accelerate the growth.

If there is a fear about the losing the job due to failure, they will be scared to execute a change. Instead, they try to stick to safest route to save their own ass. It is the dangerous thing to happen to an organization because that organization will die due to the lack of innovation. We have read about the companies like Kodak, Blackberry, Nokia etc. those who forgot/late to make much needed changes.

Egg or Chicken first? I don’t care.. I eat both

Do you see your ideas are not accepted by your management because you are not so experienced as others? If yes, I think it is not right.  Experience always play good role in taking decisions and selecting a solution which is right but that should not be limiting in accepting ideas from others.

I just read this below caption from a restaurant in Chennai. It was an interesting caption.

It is important for every team to build a culture to encourage everybody in the team to come up with ideas and award them for the good ideas. It would help the team to be more innovative, innovation is key for success.

What is key for this? Good leadership team who does not think ‘Egg or Chicken First’

You don’t be that FROG in the well.

I remember I learned about a frog that lived in the well. Since frog was in the well entire his life he thought that the Well is the world and there is nothing beautiful than that until the water in the well dried and frog had to come out of it.

We should not be that FROG in the well.

Froginthewell

There are lot of things in the world that we have not learned and seen yet. We must be open to learn. You might be able perform well in your job today. But we need to think about tomorrow. The world is changing too fast, so we need to learn faster and act swiftly to survive in the world.

It is not just about learning, we also need to look around and check are we doing it properly. It this the best of doing? There are 100s of people in the world doing similar stuff differently. It is a challenge to get know about how others are doing. That is where you need to collaborate with others, engage yourself with others in the world, hear other, share your thoughts,  arranged hackathons to bring new ideas and encourage openness in the team to bring new thoughts. We never know, the ideas can come from junior in the team. Remember an idea can change your world !!!
