Lock-in and Lock-out in Cloud Computing, the danger we don't see!

Introduction With the exponential growth in the adoption of cloud services, organizations around the world are benefiting from the scalability, flexibility and cost efficiency provided by this model. There is a specific term for this, FinOps, but that is content for another article. However, dependence on cloud providers brings significant risks related to data portability and system interoperability. Two of these critical risks are the concepts of lock-in and lock-out, which directly affect governance, resilience, security and, above all, business continuity.

What is Lock-in? Lock-in occurs when an organization becomes heavily dependent on a single cloud provider. I highlight the importance of the Multi-Cloud contract, making it difficult or economically unfeasible to migrate to another provider or return to the local environment (on-premises). Who has never experienced this when planning to use a proprietary database?

Examples of Lock-in: Use of proprietary APIs that are not compatible with other providers.

Dependence on closed data formats. Complex integrations with services exclusive to the current provider (e.g. AWS Lambda, Azure Functions). Long-term contracts with heavy penalties for early termination.

Lock-in risks: Low flexibility to change strategy or adapt to market changes. Increased costs in the long term. Technological dependence on the provider's roadmap (tools) and decisions, even impacting customers' business rules. Regulatory compliance challenges if the provider does not meet specific requirements (e.g. data localization).

What is Lock-out? Lock-out refers to the situation in which an organization loses access to its data, systems or services hosted in the cloud, usually due to problems with the provider, such as bankruptcy, contract termination, cyberattacks or disasters. Not having access to data is so dangerous that it can even bankrupt an organization. Can you imagine the cost of downloading being higher than the value of the data?

Common causes of lockout:

Abrupt account termination due to (real or perceived) violations of terms of service.

Security incidents that affect service availability.

Lack of backups or recovery strategies outside the provider’s environment.

Legal issues that result in suspension of access to data.

Consequences of lockout:

Business interruption (downtime).

Loss of critical data.

Legal and regulatory impacts.

Reputational damage.

Mitigations for lock-in and lock-out

To minimize the risks of lock-in and lock-out, organizations should adopt proactive strategies and incorporate good cloud architecture practices.

Mitigation strategies:

Adoption of open standards: Prioritize the use of APIs, data formats, and services that are compatible with multiple providers.

Multicloud and hybrid architecture: Distribute workloads across multiple providers to avoid single dependency.

Cloud exit strategy: Develop and test migration and data recovery plans. Contracts with clear clauses: Include contractual clauses that guarantee data access and portability. Backup independent of the provider: Keep backup copies of data in environments external to the main provider. Monitoring of the provider's financial and technical health. Please look for more information in the SOC type I reports.

Conclusion Lock-in and lock-out are real and critical risks in the adoption of cloud computing services and we should be very concerned about them. That is why migration planning is not so simple. At the very least, we should have a Multi-Cloud environment, BC/DR plans, BIA with this information. Every migration is complex and there is no "silver bullet" that will solve all your problems. And regardless of technology, never be held hostage by just one manufacturer, as we say: Never put all your eggs in one basket.
