Cloud computing has revolutionized how companies manage and scale their operations, offering flexibility, agility, and efficiency. In this dynamic landscape, the multicloud strategy emerges, an approach that goes beyond a single cloud provider and seeks to optimize operations through the combination of different platforms.
In this text, we will explore the advantages and disadvantages of adopting multicloud, comparing it to hybrid cloud and presenting scenarios where it can be successfully applied. Additionally, we will provide insights to assist companies in determining whether multicloud is the right choice to meet the specific needs of their business.
What is multicloud?
Cloud computing has become more than just a competitive advantage in business operations; today, it is essential as it offers unprecedented operational efficiency.
Multicloud has gained prominence in this landscape. A bold strategy that seeks to leverage the potential of multiple cloud providers simultaneously—not only redefining how organizations manage their IT resources but also opening up a new horizon of possibilities.
In essence, multicloud involves using cloud services from different providers, challenging the traditional approach of exclusively operating with a single provider. It offers a range of advantages, including enhanced operational resilience.
By distributing workloads among multiple providers, companies can mitigate the risk of downtime in the event of a specific provider’s failure. This results in greater reliability for critical services, ensuring that applications remain accessible even in adverse circumstances.
Furthermore, it addresses a fundamental concern: avoiding vendor lock-in, as we will explain in more detail later on. With the freedom to choose the most suitable services from different providers, organizations can break free from the constraints of relying solely on one cloud provider. This encourages healthy competition and gives companies greater control over their IT strategies.
Hybrid Cloud vs. Multicloud: What are the Differences?
Hybrid Cloud and Multicloud are two concepts related to cloud computing, but they refer to different approaches to cloud usage.
Hybrid cloud combines resources from both public and private clouds. This allows companies to harness the benefits of both, such as the scalability and flexibility of public cloud and the control and security of the private cloud.
On the other hand, multicloud is an infrastructure that utilizes resources from two or more different providers. This enables companies to leverage the advantages of different providers, such as diverse features, pricing, and functionalities.
Why are companies adopting multicloud?
Some of the main reasons why companies are adopting multicloud are related to the various advantages that this type of strategy has been providing. Among them, we can highlight:
Each cloud provider has its own characteristics, pricing, and features. By adopting multicloud, companies can choose the best services from different providers to meet the specific needs of each workload.
Multicloud allows companies to scale their cloud resources as needed, consequently providing greater flexibility and convenience to meet the growing demands of their customers and businesses.
Sharing workloads and services across multiple cloud providers helps ensure that if one provider experiences availability issues, failures, or interruptions, the services will still be available on other clouds. This enhances resilience and minimizes the impact of potential disruptions.
Security and Risk Mitigation
Exclusive dependence on a single cloud provider can pose a significant risk in the event of technical issues, policy changes, or acquisitions that affect the service. Multicloud mitigates this risk, as services are not centralized with a single provider.
As companies can use different providers for different workloads, cost reduction is one of the benefits achieved. Additionally, companies can use multicloud to scale their cloud resources as needed, which can help avoid wastage.
Compliance and regulations
Some companies have compliance requirements and regulations that can be more easily met using specific cloud providers. With multicloud, this customization and adaptation to different scenarios can be implemented.
Avoid cloud lock-in
Avoiding lock-in to a single technological ecosystem or vendor, known as cloud lock-in, is a concern for many companies. With multicloud, it’s possible to prevent lock-in by diversifying services among different providers.
Improved user experience
The ability to choose the most suitable cloud provider for a service enhances the results achieved, impacting the end-user experience.
Challenges of adopting multicloud
It’s important to note that the adoption of multicloud can also bring challenges, such as the complexity of managing multiple cloud environments, system integration, and the need for IT teams with advanced and diverse knowledge.
Therefore, the decision to adopt a multicloud strategy should be carefully evaluated based on the specific needs and goals of the company. To help you analyze the pros and cons of investing in this approach in your company, we have outlined the objections that may be encountered in this process.
Dealing with multiple cloud providers increases the complexity of resource management, monitoring, provisioning, and security. Each one may have different interfaces, policies, and tools, requiring additional effort to maintain a cohesive and functional environment.
Security and risk mitigation are one of the benefits of multicloud; however, on the flip side, protecting data and applications in such an environment can also be challenging. To prevent the benefit from becoming a problem to be addressed, it is essential to ensure that your cloud resources are safeguarded from security attacks and breaches.
Integrating applications and services across different cloud providers can be complicated. Organizations need to ensure that their workloads can communicate effectively and exchange data seamlessly, which may require additional development and integration work.
While multicloud can assist in cost optimization, it can also lead to hidden costs, such as data transfer fees between providers, increasing complexity in cost forecasting and control.
Multicloud and security: understand the points of attention
Just as it occurs in different aspects of adopting technologies and solutions in a company’s daily operations, security is a critical consideration when adopting a multicloud strategy.
As we have already discussed when addressing the challenges involved in implementing multicloud, distributing workloads across multiple cloud providers increases the complexity and challenges related to data and system protection.
Therefore, it is important to be aware of and highlight security concerns when adopting multicloud:
- Unified Visibility and Monitoring: Maintain unified visibility and monitoring tools to detect malicious activities across all clouds.
- Identity and Access Management: Implement consistent identity and access management to prevent security breaches. Using identity management solutions, two-factor authentication (2FA), and single sign-on (SSO) can help strengthen access control.
- Consistent Security Policies: Establish clear and consistent security policies that apply to all utilized clouds. This includes defining firewall guidelines, data encryption at rest and in transit, password policies, and other security controls.
- Encryption and Encryption Keys: Ensure proper encryption is used to protect sensitive data.
- Anomaly Monitoring and Intrusion Detection: Implement security monitoring systems to identify suspicious activities or anomalous behavior across all clouds. This can help detect threats at early stages.
- Data Backup and Recovery: Have robust data backup and recovery strategies that span all clouds. This ensures the ability to restore critical information in case of data loss or incidents.
- Security Testing and Risk Assessment: Conduct penetration testing and regular security assessments to identify vulnerabilities and ensure security measures are effective.
- Dedicated Security Team: Maintain a well-trained and up-to-date IT security team to address multicloud-specific challenges.
