The process of cloud migration entails shifting a business's digital assets—ranging from data, and applications, to entire operational processes—from an on-premises infrastructure to a cloud-based environment. This move is primarily motivated by the desire for enhanced scalability, flexibility, and potentially, cost savings.
Understanding the Basics of Cloud Migration Costs
However, the financial outlay for cloud migration is not one-size-fits-all; it significantly depends on factors like the volume and type of data being moved, the scale of the operations, the complexity of the existing systems, and the cloud service provider chosen. Recognizing these determinants is crucial for accurately estimating the cost involved in cloud migration.
What Does Cloud Migration Cost Contain?
When you embark on a cloud migration project, there are many expenses to consider, when creating a comprehensive budget plan:
The Cost of Setting Up Cloud Infrastructure
A major portion of cloud migration expenses is attributed to infrastructure costs, which encompass cloud servers, storage, and networking fees.
However, many businesses underestimate the costs of actually setting up the cloud infrastructure. Setting up the requisite cloud infrastructure entails a variety of tasks, including provisioning for compute and storage capabilities as well as configuring the network.
This process, orchestrated by a DevOps team or an individual, hinges on the complexity and breadth of the application components. Simpler setups might lean towards the lower end of the cost spectrum, whereas more elaborate infrastructures will demand greater resources and financial investment.
The Cost of the Cloud Provider
Choosing a cloud provider involves navigating through a maze of service fees, which are relatively straightforward to calculate. The decision of which provider to choose should take into account several factors such as required services, regional availability, compliance requirements, and preferred technologies. This step is critical in laying down the foundation for the cloud architecture.
With cloud providers offering a variety of pricing models, it's essential to meticulously evaluate the needs of your organization to opt for the most cost-effective strategy, avoiding both over and under-provisioning.
The Cost of Data Transfer
Often underestimated, the expense related to data transfer to and from the cloud can add up, especially for organizations with substantial data volumes. The charges for data upload and download vary across cloud providers and are influenced by the type of storage used. It's imperative to assess this cost carefully, considering both the volume of data and the storage technology (SSD vs. HDD) in use.
Post-Migration Costs
Beyond the initial migration, ongoing costs must be factored into the budget. These include regular service fees for using the cloud infrastructure, personnel expenses for monitoring and maintenance, and any additional costs for tools required for effective management of the cloud environment. We’ll jump into greater detail on this aspect in the next section.
Factors Impacting Cloud Migration Costs
Now that we understand the general costs of cloud migration, let’s take a look at the more specific factors that will affect your cloud migration costs.
- In-house or third-party technical talent: The expertise required for a smooth cloud migration often means engaging with specialized roles such as Cloud Architects and development teams. These professionals are instrumental in designing and implementing the cloud infrastructure, with their compensation reflecting their critical role in the migration process.
- Licensing and software: Migrating to the cloud might require new software licenses or adjustments to existing ones. The costs associated with these licenses, along with compliance with licensing agreements, are crucial considerations in the migration budget.
- Downtime and business disruption: The migration process can lead to operational downtime, translating into direct financial losses. Minimizing downtime through strategic planning is essential for reducing these indirect migration costs.
- Security and compliance: The integrity and compliance of data and applications within the cloud are paramount. This often necessitates investments in additional security measures and compliance or code audits, which can substantially add to the migration costs.
- Data backup and recovery: While cloud providers offer backup and recovery services, these come at a cost. Organizations need to align their backup strategies with their budgetary constraints to ensure data integrity and availability.
- Cloud Consulting: When a business decides to migrate its data and applications to the cloud, it comes with risks. We recommend that most businesses considering a move to the cloud should factor in the cost of third-party support, as it's unlikely they will be able to complete the process without assistance. The amount of help required will depend on how much data needs to be transferred and if they have developers on staff who can migrate and deploy existing applications on the cloud.
Hidden Costs in Cloud Migration
The financial planning for cloud migration extends beyond the immediate expenses of setting up infrastructure, the cloud provider subscription, and data transfers. There are other costs that may be less obvious that might affect your long-term budget.
Post-Migration Costs
Another cost you will have to factor into the overall pricing of your cloud migration is the cost of management post-migration. How will you maintain and improve your cloud environment? Will you be growing your IT team, or can your current team handle it? Will you be outsourcing some of your management? Also, think about the costs of training employees on any new systems or apps post-migration.
The costs to consider after migration include, of course, the ongoing payments to the provider to use the cloud services, compute, and space. This is something that the provider can quote you on, so calculating the total cost of maintenance isn’t too difficult.
The other costs include costs for manpower to monitor and maintain the infrastructure and applications (CloudOps or SREs) and any software tools that may be used for monitoring and management of these systems.
Re-writing applications
Depending on the programming language or database used, applications may need to be rewritten to work as cloud native. One of the major costs to take into account here is estimating the amount of time the developers need to rewrite the application.
A longer rewrite will naturally lead to a greater cost. Unfortunately, this is one of the hardest costs to estimate as it’s almost impossible to tell how long a rewrite will take. It can be anywhere from a short 7 days to several months or so. A reliable partner with expertise in legacy modernization services should be able to shed light on the timeframe and costs associated with a rewrite.
Infrastructure spin-up
DevOps team members are development engineers who create infrastructure using code to create the resources needed for the cloud. This is similar to the process that developers do when writing and rewriting applications but the time the DevOps team members need to complete their tasks is usually easier to estimate.
When spinning up your initial resources on the cloud, be as accurate as possible to make sure that infrastructure is not overprovisioned. You will also want to very closely configure your auto-scaling capabilities since having resources scale up and down excessively can also drive costs up. Every time that a resource is scaled back down it will also incur a “cool-down” cost while the resource is still active, even if it is not currently needed or being used.
