Rules for your 1st Cloud Steps

Your  might be considering Cloud for any of the following reasons:

 

You Need  Cheap Secure Offsite Backup. The Cloud can be an effective way to achieve this.

 

Your Server Hardware is Old. You have some applications running on a server that is aging and ought to be replaced. If “Cash is King” then saving the capital expense might be useful.

You’d Like to Reduce Your IT Costs. Sometimes a service that is currently provided in house such as email can be delivered more effectively (and possibly cheaper) by a Cloud Service Provider (CSP).

Whatever your drivers are, it is essential that you resolve the following important issues!

 

Choosing the CSP. There are a number of providers. Which one(s) are a good fit for your business?

Account set up. The last thing you need is to set up the account in a way that will leave you frustrated later.

Cost Management. You need to be certain that costs cannot escalate horribly because of a poor design.

Security is essential. How can you be 100% sure that your data (and your customer’s) data is secure?

 

This blog expands on the topics above. I would be delighted to assist you with investigating and providing solutions for any of these. Insperitas is also able to provide support for Cloud solutions.

Choosing The CSP.

The three largest providers are also the most flexible

Amazon Web Services (AWS) is the largest CSP on the planet and offers a very wide range of services. The tools are relatively well known and can be adapted easily. For many this is the go-to place when beginning a Cloud Journey. https://aws.amazon.com/choosing-a-cloud-platform/

 

Microsoft are good at providing a Cloud version of services that they would traditionally provide by selling applications. Email is a classic example. For larger companies MS also offer a mature Identity and Access Management Solution based on Active Directory. Microsoft have a large network of partners and are “Enterprise Ready” in the sense that they are the oldest and most mature of the Big 3 CSPs.

 

Google are slightly newer to providing Cloud Services when compared to AWS. Google Cloud Platform (GCP) provides a much smaller array of services than AWS. However the services which they do provide are very well executed. They have a stated aim to be the largest CSP in the world in the next few years. https://cloud.google.com/why-google/

Setting up the account

The important things to ensure when it comes to setting up your account in either AWS or in GCP are:

  • Dont get locked out! You need MFA but who will have ultimate control?
  • For AWS choose a good Phone number.
  • For Google, will you get an enterprise account or a Gmail account?
  • How can you give access to another account for support?
  • Can you make use of free services?

Managing Costs

If you have teenagers in your house you will well understand the difference in attitude to electricity use between bill-payers and non-bill-payers (also known as freeloaders). When you are using your own hosted infrastructure you only have to make sure that you don’t fill up the hard drive or place too many demands on memory and processor. However when you use Cloud Services you need to be sure from day one that you will be warned if your monthly costs are going above your anticipated levels.

 

In addition you need to be sure that your costs are allocated correctly. This isn’t difficult but demands that you follow good Cloud practices right from the start.

Security

When I setup one of my first Cloud servers I was a little surprised to find out a week later that a virus had been installed on the server. I had left open a port to the server that could have been disastrous. These days whenever I build any service online I start with ensuring that it is secure. This isn’t complicated but it is necessary.

Lesson 3: Infrastructure as Code (IaC)

Because all services offered through the major cloud providers are exposed via APIs then you can start to codify your infrastructure.

To explain this in more detail lets look at the different ways we can build a server in AWS. AWS servers are called “EC2 instances” (ECC stands for Elastic Compute Cloud). Once you have an account you can use your browser to visit a console where you can click on a button to build your server. The form will ask you a bunch of questions and then Amazon will build the virtual server for you.

However Amazon also allow you to build your server from the command line. You can download the AWS SDK or you can use the CLI.  These tools will allow us to write code that can be executed to build whatever we need. There are other tools (such as Ansible and Terraform) that can add a level of abstraction and simplification to this process.

Once all of your infrastructure is built as code things start to change in the way the infrastructure is managed. We can start to introduce all the good practices that developers have been using for years to manage code. Simple things such as versioning, keeping backups of previous versions, extensive in-line commenting to name but a few.

Our code can tell our Cloud Service Provider (CSP) what to build but also tell us what we have built removing the need to continually update a database  that references our complex environments. Infrastructure change becomes easier to manage as we can roll back to a previous version in minutes.

But our code can do even more than this. Our code can include references that allow automatic scaling of services. However that demands an understanding of the subject of elasticity and at this point its probably worth reviewing the 10 principles of a good Cloud strategy.

Lesson 2: Using Cloud or Embracing Cloud

Continuing with the analogy of electricity, if your company decided to build a new motor or machine that would be driven by electricity you would likely build it to utilize the service that is commonly available. ie. 230 Volts, Single Phase, Alternating Current. You might choose something different if you had a particular need but it would be unusual to specify some random voltage just because you can. Also if you had multiple electricity suppliers are available you MAY not want ton tie yourself to a specific provider unless there is a clear benefit.

So it is with Cloud Computing. If we think of Cloud as simply a bunch of servers off site then we are missing 95% of the benefits. we could just lift and shift our existing server estate and provision it from a Cloud Service Provider but that is unimaginative and prosaic.

The right approach is “embrace” Cloud. This will necessitate a complete change of mind set within your current IT world!

One reason for this is that Cloud Services are charged for by the minute or by the hour (depending on some basic choices) and therefore you should only build EXACTLY what you need to consume. Most servers only operate at a small fraction of their capacity for most of a day. Traditional server estates are designed to be much larger than needed to be able to cope with spikes in demand. Cloud Servers should be stopped when they are not being used and therefore you wont need to pay for them.  It wouldn’t make sense to have someone on standby to start and stop machines when needed either. So therefore all Cloud Services SHOULD be consumed programmatically!

Once we have taken that important leap in understanding we are well on the way to EMBRACING rather than USING Cloud. In my next post I will get to IaC to describe why this is such a BIG THING. 🙂
