If my company has given the business case a go and the result says we should adopt the cloud. That said, technical wise from top to bottom, what are key successful elements to consider the pros and cons of? |
Answer» Numerous success factors that should be thought about are:
Start with development and testing environment first. Leave the production system and its configuration out to minimize the probability and more importantly impact of the concerns you may encounter.
Choose to move the lowest time and mission-critical systems because if there is any incident, your organization’s business will suffer.
Identify and migrate the systems with the simplest architecture as the ACTION will be considered as low risk.
Assess your systems entirely then decide which one you are keen to migrate. Analyze minimum specifications, configurations and actual usage in various situations (high, medium, low workload). Upon completion, identify and choose the APPROPRIATE cloud environment to match, whenever and wherever possible, all your organization’s requirements.
Be mindful of the licensing including the model and cost as well as Terms and Conditions of the cloud service (IaaS, SaaS, PAAS) and model (public, private, hybrid) you will procure ever SINCE they differ from vendor to vendor and cloud service provider.
You should assess and evaluate SLA thoroughly including the compensation if the provider is unable to achieve the agreed metrics.
Ensure that you identify and discover application/system dependencies to avoid unplanned outages and limited functionality that usually occurs when the migration is completed.
Review each architecture (Application, Data, Infrastructure) comprehensively to achieve optimization of the cloud platform.
Inquire about the processes, activities, methods, tools needed and or offered by the provider to migrate from their cloud into another cloud.
Ask the provider on their network availability and bandwidth requirements because you and other end users will be accessing cloud services and products anywhere, any time. |
