How to choose the cloud that suits your needs

The idea of entrusting your sensitive data to a third party was still unthinkable just a few years ago. Today, many companies are outsourcing their information system to cloud providers. With the wide range of offerings on the market, however, choosing a provider can rapidly become a challenge. To help guide you through this choice, Mehdi Bekkai, product manager of cloud computing at OVH, shares his expert opinion on the right way to adopt the Cloud.

I am gradually developing, testing and building up my activity…

VPS (Virtual Private Cloud) is one of the simplest solutions on the market for trying out the Cloud. Users benefit from ‘root’ access to the VPS and can manage the service like a dedicated server, the difference being that it is administrated by the service provider. This server is just as suitable for developing applications as it is for hosting a standard website or a small e-commerce site. Ideal for new businesses, VPS is a major step in transitioning to the Cloud and represents an opportunity to test out cloud conditions on a virtual server at the best value for money.

The OVH advantage: “VPS allows you to focus on your project by freeing you from administrative constraints and the challenge of choosing applications and environments. At OVH we offer performance oriented (SSD), high availability (Cloud) and enhanced RAM VPS options with triple replicated data. To all this we add a Plesk offering, which includes many preinstalled services like WordPress and PrestaShop.”

I have made up my mind; I am going into the industry…

‘Public’ Cloud operates through a network of physical servers, forming the base of an infrastructure in which several dozen instances (or virtual servers) can be deployed within a few minutes.

Oriented towards engine or ‘compute’, performance, this offer is well suited to large-scale data processing, high-performance computing (HPC), streaming or hosting bigger e-commerce sites. The fast deployment of instances means it can deal with high traffic on a website and ensure high availability.

The OVH advantage: “With the pay-as-you-go payment model of Public Cloud instances, you pay for each of your instances by the hour or the month, and you can deploy or deactivate them quickly as and when you need to. Virtualisation is done by OpenStack technologies, so it can be automated (API) and reversed. This means the customer can migrate their infrastructure and configuration to Public Cloud whenever they choose to do so.”

I need to store, protect and retain access to my data…

Beyond data processing, the Cloud also represents an excellent way to store data, independently or as part of a "compute" offering. There are two different types of storage depending on your needs:

“At OVH, Public Cloud Storage is focused on data storage or backup in the Cloud. It exists in two forms: if you need unlimited data storage and require access to your data at any time (for an e-commerce site for instance)Object Storage is for you. For long term archiving with deferred retrieval (data access is not immediate), the less costly Cloud Archive is ideal. Cloud Archive is suitable for occasional (multimedia, old catalogue, etc.) or regular (balance sheet, dematerialized admin, etc.) archiving needs,” adds Mehdi Bekkai.

The OVH advantage: “With OVH Object Storage, your data is triple replicated and highly protected.”

I want to manage my own datacentre remotely…

Private Cloud is recommended for companies that want to place their critical/sensitive productions or applications in the Cloud. In a ‘single tenant’ configuration, each customer is the sole user of a scalable infrastructure that is completely dedicated to guarantee an optimum security policy.

This configuration allows you to build and control your own infrastructure according to your specific needs: hosting websites, applications, Software as a Service (SaaS), software packages (management tools for companies), etc.

“OVH Private Cloud exists in two packages: first with Dedicated Cloud, a versatile solution that offers the best price/performance ratio. Meanwhile, Software Defined Datacenter (SDDC) is a high-performance cloud for building and managing your own cloud, integrating a network management solution (NSX). This package is available on an international basis, identical in all OVH datacentres.”

The OVH advantage: “Access to the VMware hypervisor (licences included) allows you to create unlimited virtual machines. The starter packs are delivered in 30 minutes, additional physical resources in 5 minutes. What is more, Private Cloud even has the certification required to host banking data (PCI DSS).”

I cannot decide between Public and Private…

Performance and/or storage, data sensitivity, traffic fluctuation and more: there are so many variables that make each cloud infrastructure unique. It can be hard to decide between Public and Private Cloud. “With vRack, OVH allows you to mix and match these different technologies in a unified infrastructure, so you can optimise the way you use each product. For example, many OVH customers place their core business in a Dedicated Cloud, and manage burst by deploying instances on the Public Cloud.”

The OVH advantage: “This package applies to multiple products. On the vRack (the OVH private network), you can connect different packages from different datacentres, wherever they are in the world, and stay closer to your customers.”

And what about my existing network in all this?

Some companies have their own infrastructures and want to keep them while expanding on cloud infrastructures via an on-premise/off-premise configuration. “To respond to this specific need, we have developed vRack Connect. This works for companies that want to keep part of their production or their data on their own network and outsource the rest to the Cloud in order to benefit from the on-demand scalability and resources. In sum, vRack Connect represents the best compromise for keeping a foot in your physical network while enjoying the elasticity of the Cloud.”

The OVH advantage: “With a shared or dedicated connection (up to 10 Gbps guaranteed), vRack Connect is available via the worldwide PoP (Points of Presence) network. In addition to this network, OVH is developing an ecosystem of partners like Equinix Cloud Exchange so we can more easily activate interconnections with our datacentres.”
