Cloud Migration Risks: Hidden Challenges Businesses Must Know

The changing landscape of organizations is in many ways attributed to the usage of cloud computing technology. Organizations of all sizes (i.e., small startups to multinationals) have begun using cloud infrastructure in order to move their applications, data, and workloads to a location where they can take advantage of improved scalability, reduced cost, and enhanced operational efficiencies. The many advantages of adopting a cloud solution come with their own set of challenges and many organizations place a focus on the positive aspects of this migration but often underestimate the challenges associated with migrating to a cloud-based solution. Migrating to the cloud without a proper plan in place may result in security weaknesses, and additional costs, or cause disruption to operations or result in compliance failures. An understanding of the risks associated with this migration is very important in order for organizations to be able to successfully make this transition.

This article will reveal some of the most common risks associated with cloud migrations, potential impacts of those risks, and give some real-world examples of how to mitigate some of those risks.

What Is Cloud Migration?

Cloud migration is the process of transferring digital assets (such as applications, databases, servers, and business processes) from a physical location that has on-premise equipment (servers) to an outside provider's (cloud) environment. Companies that migrate their solution to the cloud can choose to utilize a public cloud, a private cloud, or a combination of both, depending on the needs of their business.

The primary reasons for migrating to a cloud solution are generally based on achieving additional flexibility within their business operations, improving the performance of their operations through better resource allocation, increasing their ability to recover from a disaster, and reducing the amount of time spent managing their IT infrastructure.

Reasons Businesses Move to the Cloud

Before reviewing the risk of migrating to the cloud, first let's understand the advantages of this shift:

Reduced costs; essentially, the cost of managing hardware is reduced.

Scalability; organizations can quickly expand or contract based on demand.

Collaboration and remote access; employees can work from anywhere using their devices with an internet connection.

Speed; organizations can deploy applications in a matter of days instead of weeks or months.

Business continuity; organizations can recover faster from disasters by relocating to an offsite location.

Access to new technologies; organizations can capitalize on the AI and analytics. While there are many benefits with moving to the cloud, organizations should adequately prepare for the risks when their migration doesn’t go as planned. 

Biggest Risks of Moving to the Cloud 

Data Security Risks 

Data security is one of the most important risks when moving to the cloud. If the right security protocols aren’t in place, sensitive business data could be compromised during the migration process. Common types of data security threats when moving to the cloud include: 

• Data breaches.

• Unauthorized access

• Misconfigured systems

• Weak authentication

• Insider threats

Organizations that handle customers, financial data, or proprietary information are at a higher risk of data breaches.

Strategies to Mitigate Data Security Risks:

Encrypt all sensitive or personally identifiable information (PII) at rest and in transit.

Implement multi-factor authentication (MFA) for all users trying to log into the system.

• Regularly audit your organization’s information security practices.

• Implement a least-privilege security policy.

• Monitor all cloud resources continuously.

Compliance and Regulatory Difficulties

Numerous industries are subject to stringent compliance regulations concerning data storage and privacy. If an organization’s cloud environment does not meet legal standards, migrating workloads to the cloud can lead to compliance issues.

Cloud migration can negatively impact your business operations because applications will be unavailable during the migration process. Some common causes of application unavailability during the cloud migration process include: 

• Network interruptions 

• Migration errors 

• Application incompatibility 

• Data sync issues 

Few hours of downtime during the cloud migration process could result in lost revenue and diminished customer trust.

Real Life Examples 

GDPR Compliance, HIPAA Regulations, PCI DSS Requirements, Residency Laws. Failure to comply with any of these can result in fines, loss of income and damage to your company’s reputation. 

Ways To Mitigate This Risk 

• Review all compliance requirements before the cloud migration process begins. Use only cloud providers that are certified for the respective compliance standards. 

• Perform regular compliance assessments after you complete the migration process. 

• Document and/or retain audit logs associated with your cloud usage.

Unanticipated Costs

Many businesses expect to save money by moving their operations to the cloud. Unfortunately, because they did not plan or manage the resources properly while doing so, the total amount they spend on the cloud can far exceed what they previously paid in traditional IT.

Some reasons why businesses experience unanticipated costs include:

• Data transfer costs 

• Over-provisioning of resources 

• Licensing fees 

• Growth of cloud storage 

• Integrating with 3rd parties 

• Without adequate oversight, businesses end up spending more money in the cloud than they did with traditional IT.

Ways To Mitigate This Risk 

• Establish a comprehensive cloud budget for your organization. 

• Continually monitor resource utilization within the organization. 

• Use cloud cost optimization tools. Develop and apply cloud governance policies. 

Downtime and Business Interruption 

Cloud migration can disrupt business and cause applications to be unavailable as they move between the cloud and the on-premise environment. 

Causes of application unavailability while moving to the cloud include: 

• Network disruption

• Migration errors 

• Application incompatibility

• Data sync issues 

Even a few hours of downtime during the cloud migration process could result in lost revenue and reduce customer loyalty.

Mitigation Strategies

• Adopt a multi-tiered approach to migrate

• Migrate during Hours of Minimal Use

• Complete system testing before all users see it

• Have a rollback plan ready if needed

• Risk of Data Loss

Not following proper procedures during migration can create the possibility of an accidental loss or corruption of business information that is critical to the operation of a company. If there is no backup of data, there is a chance that this information may become unavailable.

The most common reasons for data loss include the following:

• Human error

• Partial Transfer of data from one system to another

• Failure of a system

• A file that is corrupted

The inability to access business-critical data may severely restrict the continuity of your business operations, as well as cause loss of confidence of your customers.

Mitigation Strategies

• Perform full backups of all your data before migrating

• Verify the integrity of data received after migration

• Implement appropriate disaster recovery plans

• Perform test migrations in a test environment (staging)

Risk of Vendor lock-in

Vendor lock-in refers to a situation where a business becomes very reliant on one particular cloud service provider and will lose the ability to select an alternative vendor, making it difficult or cost prohibitive to change vendors in the future.

• Vendor lock-in limits:

• Flexibility of the business

• Ability to negotiate with the provider

• Options for future technology

• Ability to control costs

In addition, some businesses are locked into contracts for long durations or with proprietary technologies.

Mitigation Strategies

• Utilize open standards whenever possible

• Utilize a multi-cloud strategy

• Design applications that can be moved to another environment

• Carefully review the terms and conditions of all contracts

Risk of Performance Problems

When migrating applications from one service provider to another, many applications do not perform as expected because of changes to the infrastructure, latency caused by changes to the network, or due to an incorrect configuration.

Possible consequences of the performance problems include:

• Slower response time for the application

• Reduced productivity of the employee using the application

• Poor customer experience

• An increase in the number of support requests being submitted for the application

Mitigating Strategy

• Perform testing on performance prior to migration

• Optimize the workload for a cloud environment

• Continuously monitor the performance

• Adapt resources based on demand

• Skill and Knowledge Gap

Cloud environments require specialized knowledge and skills. If an organization does not have personnel skilled in cloud technologies they will make configuration errors and create vulnerabilities in the enterprise’s overall security.

Challenges associated with skills and knowledge gaps may include:

• Limited knowledge of cloud-based architectures

• Poorly managed resources

• Misconfigured security policies

• Inefficient deployment methods

Mitigating Skill and Knowledge Gaps

• Invest in cloud training programs for employees

• Obtain skilled cloud professionals

• Partner with a migration specialist or consultant

• Establish a framework for governance of the cloud

Integration Challenges

Most organizations are dependent on legacy systems which may not be easily integrated into cloud platforms.

Integration challenges may result in:

• Data inconsistencies

• Workflow bottlenecks

• Application failure

• Decreased productivity

Mitigating Integration Challenges

• Conduct thorough assessments of existing systems

• Utilize integration platforms and APIs wherever possible

• Transform legacy applications when appropriate

• Perform extensive testing on all integrations

Insufficient Planning for Migration

A lack of adequate strategic planning is often the primary contributor to unsuccessful migrations. Hastily migrating can cause organizations to overlook critical technical and business needs . Poor migration planning can lead to: 

• Missed deadlines 

• Budget overruns 

• Security issues 

• Business disruption 

How to Avoid Poor Planning for Migration: 

• Create a detailed and comprehensive migration plan Set clear goals and milestones for the migration process 

• Involve stakeholders throughout the process 

• Perform risk assessments throughout the migration project.

Advice on How to Reduce Cloud Migration Risk

To increase the likelihood of success, companies follow these best practices:

• Conduct an Evaluation that Examines All Areas

• Evaluate applications, infrastructure, interface connections and their dependability to evaluate volumes of workload that need migrating to the cloud.

• Develop a Strategic Plan for Your Migration to the Cloud

Decide what strategy you will take in transitioning your systems/ workloads to the cloud. Some of the most frequently chosen strategies are:

1. Rehost (Lift and Shift)

2. Replatform

3. Refactor

4. Rebuild

Prioritise Security with an Integrated Approach

Security needs to be included as part of every phase throughout all stages of performing a migration.

Test Thoroughly Before, During and After Migration

Document all systems within databases through various stages pre, during and post-migration for reliability in identifying any issues as soon as possible.

Sustain Monitoring Post Deployment

Cloud migration does not end once applications have been put into production. Continuous analysis should be ongoing to ensure cloud applications are running optimally, safely and economically.

The Future of Cloud Migration

Organizations are using new hybrid or mixed-model cloud technology and multi-cloud architectures to minimize their risk of reliance on one type provider. Cloud technologies such as AI (Artificial Intelligence), Automation and cloud-native architectures are allowing organizations the ability migrate in a more efficient and less risky manner.

Organizations need to remain vigilant regarding challenges related to security, regulations and operations. Moreover, a successful cloud migration will require an organization to manage more than simply moving data--great success requires thorough investigation, in-depth management of risk, on-time performance accountability to all parties involved, and continuous optimization of all processes associated with their cloud migration strategy.

Final Reflections

There are many opportunities for growth, improvement, and efficiency that come with migrating to the cloud, but there are also many different risks associated with migrating to the cloud that businesses cannot simply ignore. Potential issues for companies such as security concerns, compliance issues, outages, data loss, lock-in with vendors, and going over budget can all negatively affect the migration process if they aren’t properly managed.

Organizations will be able to confidently migrate to the cloud by understanding these risks associated with cloud migration as well as putting into place strategies to proactively mitigate these risks; this way they will have the confidence they need to make this transition while also protecting their business, data, and overall goals and objectives in the future. Properly planned migrations can minimize interruptions and maximize the benefits of utilizing cloud computing.
