Why don't you try Openstack (without getting your hands dirty)?

Is Openstack ready?

But, more important: are you ready for Openstack? 

 

Openstack is mature (but complex).

Surveys and statistics show that Openstack is mature and provides a number of benefit to a broad spectrum of users, from small to large enterprises and service providers.  

Almost every professional in the IT (including CIOs and CTOs) knows the advantage that Openstack would offer to his organization.

But many are also aware of the complexity of the technology, the need for new operational processes and skills to set up and operate Openstack.

A scalable and reliable production environment is different from a lab where you explore the capabilities of the new platform.

The journey to a mature adoption of Openstack is not easy and you need to invest time and money.

In addition, when you hire people (or train yours), there is a possibility that another company steals them with the offer of a better salary, given the scarcity on the market.

So, many IT organizations - excluding cloud service providers, because that’s exactly their business - started wondering if it’s worth spending time in running the infrastructure, rather than running their business applications.

If you are not a cloud provider, that makes money selling IaaS, why should you dedicate additional effort to installation, monitoring, troubleshooting and release upgrades to ensure reliability and performances to your applications (that’s the only asset you should care of, because your business relies on them)?

Focus on your real business.

Why don’t you delegate all the responsibility to a provider, signing a contract that puts the above tasks and SLA on them?

Doing so, you would be free to use Openstack, getting all the benefit that you expect from it, without the burden of the learning curve and the organization implied by the Openstack adoption.

You would focus on using the infrastructure to develop and run your applications, no longer on running the infrastructure itself.

That is called a managed service.

You own the infrastructure and exploit the value of your Data Center assets (you don’t just drop them to escape to a public cloud).

An expert team (it’s just their business) installs Openstack in your DC and operates it everyday in a HA (high availability) configuration, granting 99.99% uptime.

They take care of all the version upgrades and the compatibility of all the new features released by the community by using a certified configuration.

The user interface (the Horizon console, the Openstack API and command line interface) is available to you so you can deploy virtual server instances, networks, storage at will. You get complete and granular reporting on the health of the system and its performances.

You are the owner, but you don't get your hands dirty with the complex stuff   :-)

You pay them for the service, they grant you the SLA.

Just taste if you like Openstack.

The approach described above can be a strategical decision, because you want to focus on your business applications.

But you could also use this trick to stand up a Openstack environment in very short time, test it (I mean if your organization adapts to it, if your applications run well, if the operational model - IaaS at home, on your infrastructure, no cloud provider lock in - is good for you, if your developers are more productive) for a while, e.g. 3 or 6 months, and finally decide if you want to adopt it. 

At that time you can choose between continuing with the managed service or doing it yourself.

It is a zero risk trial of the technology and of the processes: if you don’t like, you haven’t wasted any time and effort to stand it up so you can happily retreat.

You simply do not renew the service contract and that’s all: you have made a real informed decision about the adoption of Openstack.

Cisco Metapod: Openstack as a managed service.

Cisco has a offer that allows you to do what I described above, that comes from the acquisition of a company whose business was exactly Openstack as a managed service, on your premises.

They had a Openstack distribution of their own, optimized and hardened to provide a smooth and effective service.

Now, thanks to a strong partnership with Red Hat, the team is using the Red Hat Enterprise Linux Openstack distribution (OSP8, based on Liberty).

The essential features of this service are:

- easy start: entry level contract for 90 days

- ready to go live in 2-3 weeks from the engagement

- HA included

- the infrastructure to run Openstack can either be yours or provided by Cisco

- both the Openstack API and the AWS API are exposed by the system

And the infrastructure to run it in production can be as simple as this:

The value you can get from it: a well defined SLA, installation included, maintenance and upgrade included, no cloud provider lock in.

I believe that Cisco Metapod is a very good option to start with Openstack.

You can put your foot in the water to test the temperature, then decide to take a bath if you like it.

Become a cloud provider in 3 months

This is the story of a company that decided to become a Cloud Service Provider.
They were already a successful IT outsourcer in the financial industry, with many customers' environments running in their data center.
Outsourcing was a healthy business but they started having some challenges, due to slow and inefficient provisioning processes and operations.
Any new request from a customer started a new project, so their customers started exploring public cloud services to get more flexibility and speed.
For this reason, the company decided to adopt the cloud delivery model and to offer their customers a self service catalog.

Of course a cloud project cannot be done in one night, so they were cautious in their approach.
Both technology and operational processes needed to be proven before embarking in such a challenge, but the traditional waterfall methodology made the expected return appear uncertain and distant.
To make things worse, they had tried to implement a PaaS project with a different vendor and they had spent a lot of money without tangible return.

I was engaged to support the evaluation of a new IaaS catalog that could evolve to PaaS and to self service applications management.
I made sure that the Business and IT strategy were in sync and I proposed to start with small steps to validate the approach. I also invited them to qualify the quick wins that they would expect to justify the investment and show the stakeholders an immediate return, so that the project lived enough to reach the expected success.
As you know well, many projects last too much and die before showing any business return.

We analyzed the current situation and defined a future vision. This was the driver for a gap analysis and for the prioritization of user stories, that we decided to implement in short iterations (sprints of 2 weeks, according to the Agile Scrum methodology).
Their data center was mainly based on Cisco networks and servers, but this was not the main reason for selecting the Cisco software stack for the cloud project.
After the initial workshops, some product demo and talks about other projects they understood that our people - and our partner company that implemented the project with them - were experienced enough to plan the project seriously and to chase the quick wins that we all considered so important.

The Cloud Management Platform chosen for the project was the Cisco ONE Enterprise Cloud Suite (aka ECS).

One of the most important features considered in the decision was the possibility to create flexible templates, later exposed as self service options in the end user catalog, for the deployment of complex applications. A set of servers with different roles, and all the networks needed to make them work, can be provisioned as a dedicated and virtually separated environment (multi tenancy in a shared infrastructure that offers economy of scale).

As an example, the following picture shows a environment that could be ordered - fully configured - with a single click. It is based on a component of the ECS architecture that is named VACS (virtual application cloud segmentation):

 

It was easy to engage the SME (subject matter experts) for the servers, the network, the storage and the virtualization in the customer organization and to ask them to define the basic policies that we would use as building blocks for all the services to be offered.
This model-based implementation is quicker to build and easier to maintain, and it can be exposed to the end users in a way that they understand and trust soon.

The automation that we built was considered useful by the SME (after winning their initial suspicion, because every good craftsman loves manual work) because it set them free from the manual operations that previously made their work tedious and error prone.
Delegating the configuration to an automated service gave their customers a faster service and a higher quality (no rework needed because of manual errors or missing information).

One more component in the architecture is the Stack Designer.
It is a tool provided by the Cisco ECS to create templates for application provisioning. It takes IaaS templates - made in the infrastructure management layer, that in our case is UCSD, to deploy a topology of servers and networks - and layers the software stack on top of them.

You can decide what software products (or custom applications) must be installed - and configured based on the input parameters provided by the end user - including monitoring agents and backup agents, and save this new template in the repository.
The integration with Puppet, an open source solution used to provision software applications, is leveraged to install and configure the entire software stack from the images in the repository.

The new template can now be offered as a self service option in the catalog, so that the end users don't need to install and configure the software stack themselves. A end-to-end solution is provided, up and running and ready to be used.
All the components of the ECS solution are pre-integrated and this makes the project faster than you would expect. But, since they communicate through standard protocols and open API, every component of the architecture could be replaced by an alternative product (from a different vendor or from the open source community). You should not be afraid of vendor lock in  :-)

Agile Delivery

In terms of project delivery, the following table shows the different iterations that allowed to complete the delivery in only 3 months.
But the amazing result is that at every sprint (i.e. every 2 weeks) new use cases were available in a usable environment.
The first demo to a real customer (a customer of my customer) was done after 2 months from the start of the project, and the first customer was onboarded after the 5th sprint (i.e. 2.5 months).

Conclusion

This quick win demonstrates that even complex projects like building a public cloud platform can be done in a reasonable amount of time.
The era of endless projects, based on complex technology and measured in function points, has passed forever.
There are simple solutions (like ECS) that make your work easier, but a good organization and the right methodology allow for incremental building and refinement of the solution. Every iteration of the project delivers a usable result in the production environment, and you don't need to wait the completion of the entire project to start using the solution.
If you are a service provider, you can start selling your services soon and produce a ROI.
More services will be added incrementally and the catalog will be richer at every iteration.
