Understanding the root causes of migration failures is key to cloud adoption success.

Rushing into the Cloud Migration results in failure

One of the biggest mistakes organizations make is rushing into a cloud migration without adequate planning and preparation. Driven by perceived urgency and expectations of rapid benefits, teams dive into migrating applications to the cloud without clear strategies. Insufficient upfront planning around timelines, costs, tools, and processes leads to chaos during actual implementation. Taking the time to properly design and test migration plans is essential no matter how urgent the cloud adoption goals.

Inadequate Assessment of Current Infrastructure

Many companies do not fully assess their existing infrastructure before embarking on a migration. Legacy systems may not be cloud-ready, requiring extensive refactoring. Failure to audit technical environments and workloads results in unexpected hurdles during migration. Teams need complete visibility into their infrastructure through detailed discovery and dependency mapping. This process also helps better estimate migration costs and timelines.

Setting Unrealistic Goals

Well-intentioned but unrealistic targets are a common source of failed cloud migrations. Leadership teams paint rosy visions of transitioning entire data centers to the cloud in a matter of months. Impractical expectations set up IT teams for failure. Organizations must set migration objectives based on thorough assessments and audits. A phased, iterative transition approach is generally advisable over aggressive “big bang??? migrations.

Insufficient Expertise and Business Resources

Migrating to the cloud requires specialized technical and business skills. Lack of capable staff and organizational support can jeopardize projects.

Underestimating the Need for Skilled Professionals

Cloud platforms and tools require different expertise compared to traditional data centers. Organizations often underestimate their need for professionals experienced in areas like cloud architecture, automation, and security. Building migration teams with the right skills and training helps avoid roadblocks. Engaging external consultants can help fill any gaps.

Lack of Cloud Architecture Knowledge

Designing optimal cloud architectures requires knowledge of areas like elastic computing, loose coupling, and serverless models. Legacy “lift-and-shift” migrations lead to inefficient cloud environments. Teams need to re-architect applications by taking full advantage of cloud native services and patterns. Lack of cloud architecture skills impedes successful migrations.

Failure to Train Existing Teams

Apart from new hires, companies must train internal IT staff on new technologies and processes required for the cloud. Without retooling and upskilling existing employees via training programs, organizations lack critical expertise needed to migrate and manage cloud environments. Change management and capacity building are crucial.

Data Security and Compliance Concerns

As organizations move sensitive data and applications to public cloud platforms, new security and compliance challenges emerge.

Data Breaches and Security Vulnerabilities

Public cloud environments have different data security considerations compared to private data centers. Organizations often struggle with protecting data from breaches and establishing granular access controls in the cloud. Legacy security tools may not work seamlessly in cloud platforms. Teams need to overhaul security strategies and deploy cloud-native solutions.

Compliance Challenges

Industry and government regulations related to data security, residency, and privacy pose compliance hurdles during cloud migrations. Organizations sometimes find it difficult to operate within regulatory guardrails while leveraging public cloud capabilities. Close collaboration with auditors and regulators is vital.

The Role of Regulatory Changes

Evolving regulations also disrupt cloud migrations, as teams scramble to realign their initiatives and architectures. Proposed laws on areas like privacy and data localization require companies to continually revisit cloud strategies. Failing to track regulatory changes can derail projects.

Cost Overruns

Cost savings are a major driver for cloud migrations. But inaccurate estimates and unanticipated expenditures often blow budgets.

Misjudging Cost Savings

Companies often overestimate cost savings from moving to the cloud. Workload requirements and cloud resource consumption are usually undercalculated. Without careful analysis, actual costs far exceed expectations. Cloud cost optimization must be an ongoing effort.

Hidden Costs in the Cloud

New expenses related to network egress, tooling, and managed services are often overlooked during migration planning. Ongoing subscription costs for cloud resources can mount quickly. Thinking through all direct and indirect expenditures is key for cost management.

Failing to Optimize Resources

Overprovisioning of cloud compute, storage, and network resources is a common problem after migrations. Teams moving legacy workloads to the cloud end up replicating inefficient on-premises resource usage. Continuously optimizing cloud resource allocation is essential to realize cost savings.

Inadequate Performance and Scalability

Cloud migrations present new performance and scalability considerations that organizations must address.

Performance Bottlenecks

Enterprises struggle to maintain consistent application performance when moving workloads to the cloud. Unoptimized data access patterns and poorly architected networks cause performance issues. Legacy apps also fail to leverage cloud-native acceleration services.

Scalability Challenges

Scalability is a key cloud benefit. But organizations sometimes find it difficult to easily scale resources up or down to meet fluctuating demand. Rigidly designed applications prevent realizing the elasticity promise of the cloud.

Impact on User Experience

Performance and scalability problems directly impact end-user experiences. Slow-loading web applications or dynamic scaling failures degrade the user experience. Without diligent monitoring and remediation, organizations struggle to maintain acceptable service levels.

Vendor Lock-In

Relying too heavily on a single cloud provider creates dangerous lock-in scenarios for enterprises.

Overreliance on a Single Cloud Provider

Many companies go all-in on a single public cloud platform like AWS. This increases exposure to unexpected price hikes or changes imposed by the vendor. Avoiding lock-in requires adopting multi-cloud or hybrid models.

Difficulty in Migrating Away from a Vendor

Vendor lock-in situations make it extremely challenging for organizations to move workloads or switch cloud providers. Application architectures leveraging proprietary services exacerbate lock-in. Portability should be a key requirement.

Risk Mitigation Strategies

Using open and managed services, building in support for multi-cloud APIs, and leveraging containerization all help mitigate vendor lock-in risk.

Resistance to Change

Any major IT transformation faces resistance from people and entrenched processes. Cloud migrations are no exception.

Employee Pushback

IT teams may resist moving to public cloud platforms due to concerns about job security and needing to learn new skills. Allaying fears via training and incentives is key to adoption.

Cultural Barriers

Legacy thinking around on-premises IT control and governance poses cultural obstacles to cloud migration. Leadership must drive a culture shift centered on agility and innovation.
