Cloud Architecture: interconnection and case that is concrete


The advent of Clouds has greatly changed the IT landscape in the past few years. Public, personal and even more. There are many types, each having its specific advantages. And thanks to cloud architects, it is now possible to build a hybrid, secure and infrastructure that is flexible perfectly satisfies the requirements of companies.

Today we are going to discuss exactly what is cloud hybrid ization in practice?


We can not deal with the subject of Cloud architecture without mentioning the vital interconnection. An interconnection allows data to be transferred from one environment to another in a hybrid architecture. To cite just one example, it is through it that a Cloud hosting an e-commerce site sends validated orders to the Cloud hosting the CRM so that the colocation UK is entered there.

Before continuing, let us pause for a brief moment on this word, “interconnection”. We no longer speak of “connection”, a term connoting a unilateral descent of information, but of interconnection, involving exchanges and placing all the elements connected to one another on a single level of value. It really is a positive development, extremely representative o f the idea of cloud architectures, and of what’s becoming associated with the IT landscape as a whole.

This trend accentuates the overall need for securing information systems. Indeed, it may be easier to gather information during its transfer rather than compromise the environments in which it really is saved. The interconnections, consequently, provide a chance for hackers and must certanly be totally protected. Along with that, they must be as efficient since the environments they link in order not to decrease the functioning that is overall of information system. So take both of these elements into account whenever choosing your provider.


The environments and their interconnections must, therefore, form a homogeneous whole; this is one of the reasons why a cloud architect is necessary for any hybridization project in a hybrid cloud. These experts know good practices and can above all identify the right technologies and surroundings adapted every single need.

Indeed, we often discuss connecting the cloud that is publicfor flexibility) and private cloud (for UK server colocation security), but this is only one example of what a hybrid architecture can be. We talk about hybridization from the moment an interconnection exists between two environments: thus, the best solutions are chosen to meet each need that is specific.

We could, consequently, imagine an architecture connecting the different local sites associated with the subsidiaries of friends via an MPLS, or conversely the interconnection of two public Clouds to benefit from two different technologies or simply redundancy … The main limit, apart from technical constraints, this is actually the imagination of architects!


Simply take the example of the fictitious the e-mail Shop, evolving into the B2B sector, which can be undergoing restructuring that is digital. It hosted its internal information system itself, which included, among other things, a messaging system and several company tools utilizing Microsoft technology. The business’s website and associated information system depend on Linux. The Email Shop, therefore, chooses to make to a UK colocation hybrid architecture.

The other data of the internal information system, contained in the HRIS, the CRM, etc. are however considered critical by The Email Shop Company. In the interests of data sovereignty to have them hosted on a se cure cloud that is private situated on UK soil.

It remains to choose the absolute most solution that is effective hosting its website. The website is linked to CRM but does not use any of its data considered to be critical. It can, therefore, be hosted on a cloud that is public Linux infrastructures.

We have therefore identified at least four various environments for the information system for the e-mail Shop Company: two public that is different, a private Cloud, and another private Cloud in the form of a PaaS (Platform as a Service) for Office 365. In order to manage the interconnection between these environments, supports the outsourcing of the system as a whole. The latter also ensures information security as well as the protection that is overall of IS against assaults.

Many companies now offer automated interconnection portals. They guarantee both data that are good speed, and data integrity and safety. For more information, contact our Cloud architects who’ll be thrilled to answr fully your questions!

How exactly to consider safety in the AWS cloud?

Currently, a major change is taking place in companies. Digital transformation is a very subject that is broad but with a common thread: IT security. Data security is now better and better, nonetheless, stays a problem for all, particularly pertaining to clouds that are public such as for instance AWS. But, migration to the cloud often improves the safety of its information systems.

Protected infrastructure: Protection is JOB ZERO

The cloud will attract, but frightening Rackspace colocation at the time that is same organizations could find it tough to consider having their data stored on gear they don’t get a handle on. Nonetheless, the safety of this equipment is guaranteed in full by AWS, for whom security is “Job Zero”, in other words, the provider’s first concern.

The amenities of Amazon online Services, therefore, have a very high level of security. The infrastructures have been designed to meet the security that is strong of armed forces companies and even banking institutions: this might be “safety by design” put forward by the GDPR. In addition, the AWS secur ity team, continuously available, is constantly learning and thanks that are improving the feedback from their millions of clients.

The guarantee of the safety is a large number of accreditations with which AWS is in compliance. And this is where a received idea began to appear: “My information system migrated to AWS benefits from their accreditations”: this is false! However, if you want to have your environments certified, this will be possible, because the base on which they are installed is in compliance with said certification.

And also this is where in fact the nuance is important: AWS provides cloud protection (the inspiration, the fundamentals of one’s architecture), and you offer safety in the cloud (the operational system). This dimension, the security policy, remains the re sponsibility of the ongoing business, which controls and is in charge of it.

Adopt good practices and protection tools

But, AWS isn’t just a safe infrastructure on which you must manage to setup a protected system. Migrating to the AWS cloud means building your environments on a foundation that is solid and accelerating the utilization of protection processes, benefiting from this modification to implement recommendations.

For example, Amazon Web Services strongly encourages integrating and paying attention to identity and access management, an essential component of the security of an information system or a website. And to support you, the AWS cloud provides you with a very wide range of native tools to simply help secure your environments.

Privilege isolated infrastructures with Amazon Virtual Private Cloud, and find out about cryptography tools (Amazon CloudHSM, etc.), access monitoring and logging services (Cloud Trail, etc.), interior action monitoring (CloudWatch), etc.

Another point that is strong of is that this cloud gives great freedom of automation. By using more and more automation, the risk of human error is reduced, which improves security. Amazon internet Services itself has plans to cut operations that are manual 80% each year!

AWS, consequently, poses as helpful information towards securing your systems, but above all, don’t grow the various tools without worldwide reasoning! Protection is a procedure that really must be looked at as a complete, whether your surroundings take a cloud or on-premise.

Start thinking about migration to AWS utilizing the best security

Knowing the security of AWS, you know you might be building on a strong foundation. You also know that you have to create and manage your own security policy, particularly thanks to the tools and services provided by the cloud provid er.

To implement this safety policy, give attention to your challenges. This will be a step that is necessary as indicated in our article “how to consider migration on AWS? »: Just take the time to include the safety aspect in your thinking. To limit the risks to your data, create a criticality matrix. This will allow you to determine the level of sensitivity of your data, and whether it can be migrated to the public cloud or not, and with exactly what degree of protection.

This mapping done, everything is a question of access control, code quality … in short, compliance with good security practices! 100% security does not exist, the important thing is to understand important computer data and applications well, to identify the potential risks involved while the procedure to check out to correct or get a handle on them.

Ways to get into AWS safety, based on AWS Transformation teams day:

• Understand AWS security

• Build on highly compliant, strong fundamentals

• Integrate identity and access administration

• enable detection checks

• Establish data localization and system safety

• Implement data protection

• Optimizing change management

• Automate security functions
