Multi-Cloud Storage for Seamless Data Management 721 0

Back in 2017, an AWS engineer accidentally mistyped a command while trying to debug a storage system in the cloud provider's Virginia data center. The result was four hours of chaos, with enterprise platforms like Slack, Quora, Mailchimp, and Expedia all going dark because of the outage. In the years since, cloud computing has continued to grow, including the recent ascent of multi-cloud architectures, as a vast majority of companies have left siloed data behind.

Enterprises understand they shouldn't rely on a single provider to remain operational, so they've turned to multi-cloud storage rather than using a central repository to store information. Multi-cloud storage allows companies to merge the services of different cloud vendors into one architecture to distribute their data and applications across several public, private, and hybrid cloud environments (or a mix of each).

Multi-Cloud Storage Solutions

Traditional storage solutions involve storing data exclusively within a single cloud service provider's infrastructure. Multi-cloud storage, on the other hand, distributes data across multiple cloud platforms to leverage each service provider's unique features and pricing models. This approach also offers redundancy and fault tolerance if a single provider experiences an outage or service disruption.

Types of Multi-cloud Storage Systems:



Native Public Cloud Solutions

Cloud platforms like Google Cloud, Azure, and AWS.

Marketplace Storage Services

Third-party solutions offered by cloud providers and usually involve pre-built virtual machines or orchestration software that connect pre-configured multi-cloud storage solutions.

Supplier-Integrated Services

Pre-integrated with public clouds, offering extra features and performance improvements.

Use Cases of Multi-Cloud Storage:

A traditional public or hybrid cloud environment works fine, depending on your business needs. But there are several reasons companies commonly go for the  power and adaptability of multi-cloud systems: 

  • Data Backup and Recovery:  By storing data across cloud platforms and regions, organizations can ensure that, in the event of a significant outage or disaster in one cloud, the data is still accessible from another. This redundancy makes it well-suited for long-term storage and disaster recovery.
  • Regulatory Compliance Storage: Multi-cloud allows organizations to store data in specific regions to comply with data residency laws while taking advantage of cloud scalability and flexibility. And, if you have regulated systems and data processing capacities that call for specific compliance requirements, you can integrate a compliant cloud provider and compartmentalize some of your security obligations.
  • Performance-Focused Storage: By storing data closer to end-users, multi-cloud allows you to place data in strategic locations based on user concentration, reducing latency and speeding up data access, which is particularly important for high-performance applications and services.

Multi-Cloud Database Management

Multi-cloud solutions bring robustness and flexibility to database management by allowing organizations to utilize and integrate database services from multiple providers.

Multi-cloud Database Benefits:

  • Data Protection: Better fine-tuning security controls by selecting different vendors for different storage components. By spreading data and applications across services, you can limit how much data a breach impacts and better isolate attacks.
  • Cost Reduction: Each cloud provider offers different pricing models, and using more than one means you get to leverage the most cost-effective option for each type of workload and service you're using. Not only that, but they usually have lower prices in specific regions, so companies can distribute their workloads across regions to take advantage of the most competitive pricing.
  • Avoiding Vendor Lock-In: Multi-cloud storage means companies are not beholden to any single vendor's pricing structures and service limitations. They can choose the most cost-effective option for specific workloads, including switching vendors when facing potential price hikes.

Multi-cloud Database Challenges:

  • Compatibility: While a multi-cloud system allows you to work with multiple cloud platforms, it’s still necessary to work with storage solutions that can play well together–meaning that they support the same software, data structures, and storage types (file, block, etc.).
  • Complexity: Managing services and resources across cloud vendors is challenging, especially if attempting to integrate those services as a single platform.
  • Integration: You need to integrate all your cloud services with the applications you use through APIs to avoid a collection of cloud accounts that cannot communicate.
  • Data Consistency: Ensuring data consistency and synchronization across distributed databases can be challenging.
  • Interoperability: Integrating databases and applications across cloud environments may require additional development effort.
  • Compliance: Maintaining compliance with data regulations and standards across multiple clouds adds complexity to governance and risk management.

4 Best Practices for Creating a Multi-Cloud Database

#1: Enable Portability

Data portability remains a significant challenge in multi-cloud environments due to proprietary APIs and the complexity of managing data across clouds. Often, data ends up siloed within the cloud where it originated. To combat this, enterprises can adopt cross-cloud data-sharing technologies that enable seamless data connectivity and transfer between cloud platforms.

For application portability, containerization and Kubernetes have become standard practices, allowing applications to be deployed flexibly across various clouds. Cloud vendors also offer specific multi-cloud platform solutions like Google Cloud Anthos, Azure Arc, and Amazon EKS Anywhere, which facilitate the deployment of applications across cloud services.

#2: Aggregate Data in the Cloud

With the explosion of data generation, modern enterprises face the challenge of data dispersed across several clouds, which can obscure valuable insights. Centralizing data in a unified storage solution, such as a data lake or cloud data platform, is crucial as it allows for better analysis and data-driven decision-making.

#3: Standardize Security Practices

Expanding cloud services across multiple providers increases the potential attack surface and risk of breaches. While spreading assets across clouds can mitigate some risks, a breach in one cloud can affect others. Organizations should standardize security practices and policies applicable across all clouds to secure multi-cloud environments effectively.

#4: Implement Multi-cloud Disaster Recovery

Disaster recovery is essential for business continuity, especially for organizations running mission-critical applications in the cloud. Traditional single-cloud disaster recovery strategies often rely on cross-region redundancy, which may not suffice during widespread outages. A multi-cloud disaster recovery strategy allows for recovery across different public clouds, significantly reducing the risk of data loss and service disruption during significant incidents.
