Cloud ServicesAdopting a cloud based strategy to IT means you will benefit from a more agile approach to infrastructure allowing for rapid deployment of services.
Cloud computing as an option for your business is less straight forward than it may seem.
With the commoditisation of servers, virtualisation, automation and ubiquitous network converging, providers are now able to offer “Infrastructure as a service”, “Platforms as a service” or “Software as a service” from “the cloud” and depending on the type of Cloud service(s) selected, there will be different impacts on the enterprise.
To determine whether applications can be delivered from the Cloud it is important to consider factors which include:
- The purpose of the environment(s) (development, testing or production)
- Computer power required (such as number of CPUs)
- Storage requirements
- Operating system
- Backup requirements
- Availability and SLAs
- Resiliency and continuity in the event of a major failure
Assessing each application against the above criteria can quickly help you identify which are suitable for delivery from the Cloud and which are not.
The Systal approach
Systal specialises in helping clients identify the connectivity requirements for applications moving to a Cloud based service.
Our approach is initially to help you to identify which applications are suitable to be moved to the cloud, specifically based on connectivity requirements and whether, for example, they can be accessed over the Internet. In addition you will also need to consider inter-application communications such as how much data is moved from one system to others and how “chatty” an application is (does your application speak in long drawn-out sentences or short bursts).
It is important to also consider latency (especially for short burst applications) which can result in poor performance as the latency across a Cloud connectivity environment cannot always be guaranteed. Finally, you should consider data integrity between the applications and how well protected it is.
SYSTAL Cloud Connectivity Services will initially consider the four parameters related to connectivity to a Cloud Service which are:
Each of the above will require a specific assessment, the result of which will determine choice of connectivity technology and the provider(s).
The Systal Cloud Connectivity Service focuses primarily on the connectivity between data centres and enterprise environments with a particular emphasis on rules and regulations/compliance, load-balancing, globalisation and guaranteeing continuity or a high redundancy environment.
In our experience it is always advisable to carry out an an initial assessment in order to understand to what extent existing connectivity solution is aligned with your current and future business strategies. This would include identification of requirements from regulatory authorities (e.g., in the financial sector regulators can demand synchronous replication). The connectivity solution which will ultimately be deployed to support the Cloud Services has a mandatory requirement to be able to accommodate this.
The second priority is to identify the type of connectivity needed by application and location. As an example, storage replication needs a different connectivity to that of file sharing simply because office applications are less business critical than primary business applications such as CRM, ERP and process control.
SYSTAL Cloud connectivity assessment scope
- Business requirements (including regulatory and legislation requirements)
- Basic infrastructure and applications assessment
- Business-specific applications
- Relationships between data, servers, storage and networks
- Data volumes (actual and anticipated)
- Bandwidth requirements (to peak load)
- Assignment of bandwidth per application and per location
The assessment will give an indication of the minimum and maximum bandwidth requirements and latency requirements.
SYSTAL Cloud Connectivity services benefit
Regardless of what stage your data centric computing is at, the Systal view is that connectivity is of crucial significance. We believe that a well thought and designed connectivity solution and policy should be fully aligned with the business strategy. A significant amount of cost can be saved by deploying the right connectivity strategy, and at the same time raise the general availability of the IT facilities and increasing/realising business outcomes.
