Let’s dive in:

What is Multi-Cloud?

Multi-cloud is the utilization of two or more public cloud providers to serve an organization’s IT services and infrastructure. There is no single multi-cloud vendor.

A multi-cloud approach typically consists of a mix of major public cloud providers, namely Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft (Azure), and IBM.

Organizations choose the best services from each cloud provider based on costs, technical requirements, geographic availability, and other factors. This may mean that a company uses Google Cloud for development/test, while using AWS for disaster recovery, and Microsoft Azure to process business analytics data.

Organizations that adopt a multi-cloud architecture may leverage multiple public clouds in combination with private cloud deployments and traditional on-premise infrastructure.

Data Availability Challenges in Multi-Cloud Environments

In addition to the advantages, multi-cloud adoption can present an entirely new set of challenges. One of these challenges, data availability, is the process of maintaining access to your data at your required level of performance in situations ranging from normal everyday operations to disaster recovery operations.

Individual cloud providers have already solved many of these data availability problems within the context of their own clouds or services. Cross-service consumption, cross-region replication, snapshots, and backups, are all services cloud providers currently offer to help combat data availability problems.

What happens though, when we start thinking about the same data across multiple cloud providers? Organizations would need to take on the role of coordinating data availability and security across multiple cloud providers. Ask these questions before attempting to use the same data sets across clouds:

  • How do I take the output from a service in one cloud provider and use it as input for a service in another cloud provider?
  • How do I implement consistent data management policies across multiple cloud providers?
  • How can I safely read and write to the same data set across multiple cloud providers?
  • How can I manage capacity and performance across multiple cloud providers to ensure consistent performance?
  • These are just a few examples of the data availability challenges you might encounter when implementing a multi-cloud strategy.

Multi-Cloud vs Hybrid Cloud – What’s the Difference?

Multi-cloud and hybrid cloud are both common architectures for cloud deployment, but each has its own unique definition and they are certainly not the same thing.

A multi-cloud architecture is one that includes two or more clouds of the same type. Some organizations use multiple private clouds to deliver services, while others use multiple public clouds from different vendors – these are both examples of multi-cloud architectures.

A hybrid cloud architecture solution is one that includes a combination of public and private cloud infrastructure, and which allows for orchestration between the two. Hybrid cloud architecture can also include connected on-premise data centers.

Multi-cloud and hybrid cloud deployments are not mutually exclusive. An organization that orchestrates workloads between an on-premise data center, a VMware private cloud, and multiple public clouds is pursuing both a hybrid cloud and a multi-cloud strategy.

How Secure is Multi-Cloud?

Multi-cloud security has the goal of protecting data in a consistent way across a variety of cloud providers. In a multi-cloud approach, third-party partners handle different aspects of security. During cloud deployment, it’s important to clearly define and distribute security responsibilities among the parties.

Who is Using Multi-Cloud Computing?

Organizations are continuing to embrace the multi-cloud environment, with the adoption of multi-cloud architectures reaching an all-time high among enterprises.

A multi-cloud management survey conducted in 2019 by the International Data Corporation revealed that 81% of enterprise organizations were using multiple public clouds along with one or more private cloud deployments to support application workloads while maintaining privacy and reducing IT spending.

In the ninth annual State of the Cloud Report, 554 IT professionals from public and private sector companies with 1000+ employees were asked about multi-cloud adoption within their organizations. In total, 93% of respondents indicated that their organizations had adopted a multi-cloud approach to meet their computing needs.

Another survey on cloud adoption examined how enterprise organizations were incorporating services from the big three multi-cloud vendors (Amazon Web Services, Microsoft Azure, and Google Cloud Platform) into their network architectures. The results indicated that 40% of respondents used two or more of these providers, while an additional 18% used all three providers for various application workloads.

What is a Multi Cloud Approach?

Multi-Cloud is an approach that leaves many IT leaders scratching their heads in confusion for a number of reasons. Whether the reason is lack of insight into how to leverage multi-cloud or understanding the value of this approach, we know that Multi-Cloud is here to stay. According to Gartner, multi-cloud strategies will jump from 10% in 2015 to more than 70% by 2018.


Once an IT leader buys into the idea that utilizing a multi-cloud approach is in the best interest of their organization, a new stage of confusion tends to emerge. Often they don’t know how to navigate a multi-cloud strategy and how to properly architect and manage multiple cloud vendors in an organized fashion. The goal isn’t to spread data and applications all over the internet!


Three Challenges Organizations Face with Multi-Cloud Storage

1. Finance Challenges:

  • Optimizing the cost of storage
  • Hidden (or not so hidden) egress charges
  • The development cost of re-platforming apps to move to the cloud

2. Integration Challenges

  • Lack of experience/process for integrating multiple clouds
  • Making it work with existing data
  • Making Data Fabric “real” in the public cloud
  • Leveraging existing investments (a la Snapmirror, RecoverPoint)

3. Technical

  • Multi-Cloud is hard, and often organizations don’t have the expertise on-hand
  • Managing the complexity utilizing diverse functionality from multiple clouds
  • Huge complexity integrating clouds (especially multiple clouds)
  • Big Data requirements can be tricky to handle

Getting all of the major providers, like AWS, Azure, Google, Oracle and IBM to work together so organizations can form a seamless multi-cloud is highly unlikely, so what’s the solution?


How to Tackle a Multi-Cloud Approach

In tackling a multi-cloud approach, organizations need to start with assessing their existing approach and defining a new strategy that encompasses how they manage the things that are and will always be important, such as compliance, risk, and cost control, and still have a sense of control over the management of their environment.

To address these operational challenges of a multi-cloud reality, IT teams will need the ability to visualize resources and manage performance across all environments. Only then will you enable your organization’s infrastructure to be used as a competitive advantage rather than as a risk.

What is a Multi-Cloud Strategy?

A multi-cloud environment is one that combines services from more than one public cloud service provider to meet an organization’s technical and business needs. Multi-cloud solutions can combine Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), and Infrastructure-as-a-Service (IaaS) deployments.

A multi-cloud strategy empowers organizations to increase the efficiency of their IT spending and business operations by choosing the right service and provider for each use case. Industry analysts at Forrester surveyed over 600 cloud strategy professionals to determine the leading use cases for multi-cloud architecture1, which included:

  • Selectively deploying application workloads across multiple public and private clouds based on application and business needs.
  • Combining on-premises infrastructure and services from multiple public clouds in a hybrid cloud environment.
  • Developing API-consistent cloud infrastructure across both public and private clouds.
  • Extending data-center capabilities and expanding disaster recovery capabilities.
  • Regulating access to cloud-based data, applications, and services through a single management portal.
  • Building applications with components deployed to different cloud platforms.

With 93% of enterprise organizations already pursuing a multi-cloud strategy, ongoing IT investment will focus on optimizing multi-cloud architecture and deployments to realize key strategic benefits and objectives. Let’s take a closer look at seven of the most important drivers for multi-cloud investment in 2020.

What is multi cloud strategy

Why Use a Multi-Cloud Strategy?

With adoption rates for multi-cloud climbing across industries, there is a driving force that’s pushing enterprise organizations and small-to-medium-sized businesses toward the multi-cloud paradigm.

In fact, there are several reasons why more organizations each year are choosing to implement and refine their multi-cloud strategies. Here are just a handful of reasons why we’re seeing unprecedented multi-cloud adoption rates across the information technology landscape.

7 Reasons Why Organizations Choose a Multi-Cloud Strategy

1. Avoiding Vendor Lock-In

Vendor lock-in happens when it becomes too difficult for an organization to transfer its business away from one cloud service provider to another provider or even to bring its data back on-premises.

Organizations that depend on a single cloud service provider frequently find themselves developing applications that rely heavily on the unique capabilities of that vendor. As those organizations expand their investment in that single cloud, switching providers becomes more costly, complex, and time-consuming.

In contrast, organizations that have committed to a multi-cloud strategy intentionally plan for agility and portability between multiple cloud providers. With the flexibility to transfer applications between multiple public cloud vendors, organizations are poised to take advantage of new technologies from all providers and can choose the best-performing or most cost-effective services for specific application workloads.

Adopting a multi-cloud strategy can help your organization avoid vendor lock-in, take advantage of new and better technologies from other providers, and choose the most cost-effective and performance-optimized compute or storage resources for each workload.

2. Overcoming Data Gravity

In 2020, data plays a central role in daily business operations for thousands of businesses. Organizations have traditionally stored their data in on-premise data centers where it could be analyzed by legacy applications, but in the cloud computing era, more are choosing to store data in the cloud and analyze data with cloud-based applications.

The term “Data Gravity” refers to the idea that large data sets are difficult and expensive to move or migrate, and that as a result, they must be stored in proximity with the applications and services used to analyze them. If your organization stores a large volume of data with a single cloud service provider, data gravity could force you to deploy related apps and services with the same provider – even when there are more cost-effective options available in another cloud.

Overcoming data gravity is as simple as adopting a cloud-attached storage solution that connects to multiple clouds simultaneously. The best solutions minimize latency by hosting your data in close proximity to cloud data centers. Faction Cloud Control Volumes provides these capabilities and gives you full ownership and control of your data while ensuring data portability and security. Here is our guide to learn more about Cloud Volumes.

3. Optimizing Workloads in the Cloud

Each public cloud service provider offers its own blend of physical infrastructure components and application services with versatile functionality, usage characteristics, terms & conditions, and pricing. They also release new features on a regular basis to make their services more efficient, cost-effective, and attractive for customers.

As a result, there isn’t a single cloud provider that can claim to provide cost-optimized services that cover every potential business need or use case.

With a multi-cloud strategy, organizations select the most suitable cloud service provider for each individual application or workload, leading to enhanced application performance and improved cost-efficiency.

4. Elevating Application Performance

When cloud-based application services are delivered from servers at distant locations, data must travel across several network nodes before reaching the user. As network latency increases, slow data transfers may degrade application performance and negatively affect the user experience.

The major public cloud providers (AWS, Azure, & Google Cloud) operate multiple data centers in geographically diverse regions, creating a network of availability zones that deliver high-speed service to customers and users around the world. By adopting a multi-cloud strategy and leveraging cloud services from more than one vendor, organizations can access new geographies and provide better application and data performance for their users, wherever they are located.

5. Curbing Shadow IT

Shadow IT happens when independent business units within an organization adopt technological solutions without the oversight of the IT department. Shadow IT can lead to security concerns, especially when staff members are using unsecured platforms outside of the organizational firewall to transact sensitive data. Gartner has predicted that in 2020, 30% or more of successful cyber attacks will target Shadow IT resources within enterprise organizations.

When organizations are slow to adopt new technologies, employees may choose to independently configure the hardware, software, or web services they need without involving the IT department – thus proliferating Shadow IT’s risk to organizational data security.

Organizations adopting a multi-cloud approach can accelerate their adoption of cloud services that drive employee productivity and collaboration, reducing the temptation for employees to implement new technologies without going through the appropriate channels.

6. Enhancing Disaster Recovery Capabilities

Most public cloud service providers offer 99.5% uptime as part of their service level agreements —yet unplanned outages do happen and they can be extremely costly. A 2019 survey of 100 IT directors in large US enterprises found that organizations experienced an average of 830 minutes of unplanned downtime during the year, with an average cost of $5.6 million.

With a multi-cloud strategy, organizations can respond to unplanned service outages by failing over their workloads from one public cloud to another. With Faction’s cloud-based disaster recovery solutions, organizations can customize their failover models based on application-specific needs, taking advantage of trade-offs between cost and performance to achieve a fully optimized disaster recovery strategy.

7. Meeting Regulatory Compliance Requirements

More organizations than ever now need to meet regulatory compliance requirements related to data localization or data residency. Such regulations have been passed by the European Union and at least 10 other countries around the world, including India, China, Germany, Canada, and Australia.

Data localization laws may prohibit organizations from exporting data about a nation’s residents to other countries, requiring that the data be processed and stored in the same country where it was collected. In some countries, data localization laws apply to all forms of personal data, while in others, their scope is limited to specific types of data (personal health records, payment system data, etc.).

Organizations can comply with data localization or residency laws through a multi-cloud strategy by taking advantage of cloud service providers with regional availability zones and data storage infrastructure in these countries, even while leveraging a preferred cloud provider in other countries where data localization is not required.

4 Additional Reasons

1. Flexibility

Respondents to a 2018 Forrester Consulting survey were asked to describe their organization’s multi-cloud strategy. The number one response was that organizations were using multiple public and private clouds to host different application workloads.

The ability to distribute application workloads across cloud deployments offers huge benefits.

  1. Organizations can store and maintain sensitive data in private cloud deployments or on-premise data centers to meet their data security and privacy obligations.
  2. The additional choice of multiple cloud environments gives you flexibility and the ability to avoid vendor lock-in.
  3. They can allocate different types of workloads to the best-choice public cloud environment based on requirements for cost and performance. Some cloud service providers are more cost-effective for high volumes of requests with low data storage requirements, while others may be better suited for lower request volumes and larger transfers of data.
  4. Organizations can also adopt multi-cloud to take advantage of vendor-specific features that are unique to a cloud service provider and that may offer savings or efficiency gains for a certain application workload or use case.

2. Proximity

Leveraging services from more than one public cloud service provider can allow organizations access to new availability zones that are more proximal to users, resulting lower network latency and enhanced application performance.

Let’s take AWS cloud services as an example.

Amazon maintains a global network of data centers across 24 regions, a number they claim is twice more than the next largest provider of public cloud services.

Each of these regions includes one or more availability zones, defined as data centers with 50,000-80,000 servers that use 25-30 MW of power. There are 76 availability zones in total, and those within each region are connected by low-latency, high-speed networks.

By taking advantage of these AZs, organizations can position data storage and compute resources closer to their users. This results in improved application performance and an enhanced customer experience.

3. Resiliency

Business resiliency is another key driver of multi-cloud adoption for IT organizations.

Even the largest public cloud service providers experience network issues that can result in business-impacting service interruptions for their customers.

A notable example occurred recently, on June 2nd, 2019, when a cascade of errors created a network congestion crisis that resulted in four hours of service interruptions for customers of Google Cloud Services. As Google scrambled to address the root cause of the outages, major platforms like Snapchat, Shopify, and YouTube experienced major outages with real impacts on revenue and degraded customer trust.

Organizations that adopt a multi-cloud architecture can reduce the impact of service outages by implementing a fail-over strategy that moves application workloads from one public cloud to another when a service interruption occurs.

Instead of waiting for a cloud vendor to resolve technical issues, these organizations can simply re-locate their workloads to a secondary cloud and continue business as usual — without interrupting service to customers.

4. Shadow IT

The need to standardize data access and rein in “Shadow IT” is another key driver of multi-cloud adoption for organizations of all sizes.

If you’re not familiar, the term “Shadow IT” describes situations where business units in an organization adopt cloud services and technologies independently of the IT department.

According to a 2019 study conducted by McAfee, the average company uses a total of 1,083 different cloud services – yet just 108 of them, on average, are known to IT. That leaves an average of 975 cloud services per company that fall into the category of Shadow IT.

Cloud storage apps like Dropbox or Google Drive may be used to support file sharing and collaboration between employees. Eventually, these services may become so central to the functioning of the business that it becomes necessary to manage and secure them through the IT department.

This creates a de facto multi-cloud architecture where the IT department is managing several different clouds that are in use by the business. In fact, a 2018 report compiled by IBM analysts discovered that 59% of businesses had moved to multi-cloud architectures through the adoption of cloud services by independent business units.

Best Practices to Take into Consideration Before Implementing a Multi-Cloud Strategy

  • Proactively monitor cloud and infrastructure applications
  • Align IT resources with business demands
  • Identify infrastructure needs to improve application performance
  • Look into both on-premise and public cloud costs to make informed decisions
  • Research hybrid and multi-cloud infrastructure and services you may not be familiar with
  • Prioritize automation to make migration less painful
  • Identify regulatory compliance issues before migrating

All of this is much easier said than done, so if you’re struggling to implement or manage a multi-cloud environment, we recommend leveraging a third-party to assist with the evaluation, architecting, planning, and execution of cloud migrations, and possibly even managing the new environments. Through overcoming these challenges, you can ensure a successful implementation and know that your organization is on track for leveraging the benefits of multi-cloud.

How to Choose a Cloud Data Service

Organizations are increasingly relying on cloud provider services to offload large portions of their application stacks. For example: databases, message queues, batch processing, load balancing, and traffic management, just to name a few.

If we wanted to treat data the same way, how would an organization choose a “data-as-a-service” provider? For starters, that provider would need to resolve the availability problems in a multi-cloud environment.

Let’s look at the full list of criteria:

1. Geography

The service would need to be geographically proximate to the cloud providers an organization is using. Light only allows data to travel so fast, so being as close as possible ensures acceptable levels of latency.

If the organization uses clouds located in the “US-East (Virginia)” region, they would work with Cloud Data Services providers that also reside in this region.

Not all data center providers in the region are created equal. Choosing the correct geographic location and datacenter partner can significantly improve latency, but choosing the wrong one can hinder your productivity.

Some providers offer round trip latency under 1ms to both AWS and Microsoft Azure in the “US-East (Virginia)” region. However, in the same region, other providers’ services can reach as high as 2ms round trip latency.

Choosing a provider that provides low latency to all targeted public cloud providers will provide consistent performance and improve throughput (IOPS) to the storage service.

Choosing the correct data center provider can have a significant impact on latency and performance of Cloud Data Services.

Cloud Latency Example

2. Connectivity

The service would need the ability to securely connect to the cloud providers your organization is using. The ideal service would provide a low-latency connection, with adequate throughput, to consume the storage service. This would include using services like DirectConnect for AWS, ExpressRoute for Azure, and Cloud Interconnect for GCP.

cloud connectivity

3. Consumption

cloud connectivity

Look for a service that allows all of your cloud providers to simultaneously access your data. Without simultaneous access, an organization’s choices for service consumption are limited to the public cloud where the data is accessible.

Having simultaneous access to the same data set from multiple cloud providers allows organizations to put services from different providers in head-to-head competition.

Using file systems and protocols that support file locking allows the service to provide this functionality. NFS and CIFS are commonly used to meet these requirements.

The service would also need to provide a flexible endpoint consumption model. Your organization may want to consume storage from the same IP space across all of your cloud providers, or your organization may want a unique IP space for each cloud provider.

Having the flexibility to choose which IP space you consume the data from provides organizations the ability to adhere to any existing IP schema requirements and standards. Organizations are not required to compromise the ability to consume data from a singular storage platform, while still maintaining flexibility in the data consumption methods.

Being able to consume data as a service across multiple cloud providers can change the way we think about and consume cloud services. Organizations will be able to shift from one cloud to another, or use multiple clouds simultaneously, to take advantage of cloud innovations and cost savings — all without worrying about data portability.

consumption diagram

Organizations can ingest the data using one provider, process the data with a second provider, and maybe even visualize the data with a third provider. The sky really is the limit when it comes to flexibility and innovation potential this provides.

It gives organizations the opportunity to spend less time thinking about how to manage data and spend more time thinking about how to use the data.
