Adopting cloud computing has become increasingly popular, with many
organizations taking advantage of its benefits, such as reduced costs, improved
flexibility, and scalability. However, with this increased adoption comes the
need for increased attention to security, particularly regarding sensitive data,
data classification, privacy, and Sovereign Clouds. Sovereign Clouds are managed
and operated privately or through a third-party Sovereign Cloud Provider, such
as a VMware Sovereign Cloud Provider, often used for sensitive data and
applications. Sensitive data may have a broader scope than people realize and
can vary depending on the context and the industry the company focuses on. For
example, in healthcare, sensitive data might include medical records, while in
finance, it might include financial records and credit scores. In government, it
might include classified information related to national security.

Unfortunately, many organizations still need to be more open to using Sovereign
Clouds, despite the risks of avoiding them. This blog post will explore the
risks of avoiding Sovereign Clouds and why considering them is essential.

There could be several reasons why organizations are not adopting Sovereign
Clouds:



However, avoiding Sovereign Clouds and using Hyperscale clouds can pose several
risks to an organization’s security and privacy.

 * Public clouds are typically owned and managed by third-party providers who
   may have different security controls and protocols than in your organization.
   This means your data could be vulnerable to unauthorized access, theft, or
   misuse by hackers, insiders, or other malicious actors. This is something
   recently highlighted by President Biden, that there needs to be regulation of
   the security practices in Public Cloud, which poses a considerable risk for
   sensitive data.
 * Public clouds often rely on shared infrastructure, meaning that the data and
   resources of multiple organizations are stored and processed on the same
   servers and networks. This increases the risk of data leakage or
   cross-contamination, where sensitive data could accidentally or intentionally
   be accessed or exposed to other users on the same platform. Shared platforms
   come at a functional cost, typically security and performance. Resource
   contention and degraded performance can exist depending on the underlying
   hypervisor used in the public cloud. Hyperscale clouds often limit the
   compute, network, and storage resources customers can use to work around
   this, resulting in high costs vs. resources and many customers moving
   workloads out of their cloud. Recent examples in the press are basecamp and
   37Signals.
 * Public clouds are subject to legal and regulatory requirements that may not
   align with an organization’s security and compliance needs. For example, some
   public cloud providers may be subject to foreign laws such as U.S. Cloud Act
   or government surveillance such as FISA, which could compromise the
   confidentiality and integrity of the classified data. In Europe for example,
   the U.S. Cloud Act raises concerns about the privacy and data protection of
   EU citizens, as it potentially allows US authorities to access their personal
   data without sufficient safeguards or oversight. In summary, it conflicts
   with the EU’s General Data Protection Regulation (GDPR), which requires
   companies to obtain explicit consent from individuals to process their
   personal data and ensure adequate data protection measures are in place.
   Consider data as all forms, including metadata, telemetry data, accounting
   data and support data, the sphere of influence to consider here is much
   larger than you think. Exposure has been documented many times in the press.
   An excellent example of this is the 2022 Data Protection Impact Assessment
   (DPIA) from the Dutch ministry, stating “high risk related to unencrypted
   streaming and stored special categories of data” and:

 

“There is a high data protection risk related to the possible access by US law
enforcement and secret services to very sensitive and special categories of
personal data. This risk occurs even though the Teams, OneDrive and SharePoint
Content Data are already exclusively processed and stored in the EU, because
access to this data can be ordered through US legislation such as the US CLOUD
Act.”

 

 * The organization should control the management and visibility of its data as
   it is stored and processed in a third-party environment. Public cloud lack of
   standardization can limit the organization’s ability to audit, monitor, and
   enforce security policies and procedures. Public clouds are highly
   distributed and complex, making a comprehensive view nearly impossible. This
   is compounded by a shared responsibility model for security where customers
   are responsible for using the public cloud features to secure their own data.
   The public cloud is very good at rapid scaling, which can challenge keeping
   track of security policies over multiple resources. Finally, all public
   clouds have differing capabilities and toolsets, creating challenges with the
   levels of security possible but also the enforcement of security.

Overall, the risks of putting any data in a public cloud can be significant, and
organizations should carefully evaluate and mitigate these risks before deciding
to use such services. However, is Sovereign Cloud a nirvana? Organizational
concerns about Sovereign Clouds range from the availability, performance, and
cost of Sovereign Cloud solutions to traditional cloud offerings. Are they
correct?



 

Availability

Sovereign cloud solutions may have a different global reach and availability
than traditional public cloud offerings; a view could be that this limits their
ability to support geographically dispersed workloads and users.

Sovereignty is not a global matter but a national one or shared regional in the
EU, for example. Sovereign Cloud solutions ensure high availability within
national geographies and data centers within the Sovereign region; going across
borders would mean differing jurisdictions and laws about all aspects of data
and cloud. Ensuring the availability of data and services is critical for
operations that Sovereign Cloud providers manage, such as operations of national
interest.

Availability is a crucial aspect of the VMware Sovereign Cloud 20-point
certification; VMware Sovereign Cloud partners must attest to providing data
integrity and availability with redundant infrastructure and failover mechanisms
to ensure that data and applications remain available in the attested territory
in the event of a regional outage or disaster.

Performance

Sovereign Cloud solutions, as all cloud solutions, will have different levels of
performance and scalability than public cloud offerings. This could be viewed as
limiting their ability to handle high-volume, resource-intensive workloads.

Sovereign Clouds are built and designed to meet sovereign customers’ needs; many
Sovereign Clouds operate at very high levels of availability, exceeding
hyperscale offering capabilities. Operations of National interest and specific
verticals have unique application requirements, and valuable items such as
autoscaling are available to VMware Sovereign Cloud providers.

VMware has pioneered exceptional performance, including some faster than bare
metal capabilities (see Tanzu Kubernetes example). For a long time, VMware has
had technologies to avoid performance issues inherent in virtualized
environments and has outperformed public cloud services. For a great example of
this, see this report from a VMware Cloud Provider Expedient.

Cost

Sovereign cloud solutions may be more expensive than traditional cloud offerings
due to higher operational costs, lower economies of scale, and the need to
maintain specialized infrastructure and talent.

Cost is a critical cloud component, and VMware Cloud Providers work on a pure
consumption model. Unlike hyperscale cloud, where you must purchase reserved
instances, you can have a resource pool of compute and storage and use as much
or little as you need. Resource pooling is one option for cost-sensitive
Sovereign customers, even those that want dedicated hardware and private clouds
can quickly scale out without incurring significant costs.

Sovereign Clouds deal in security and compliance; Sovereign Cloud partners
invest significantly in the enhanced vetting of personal, infrastructure and
systems aligned to the data classification and industry vertical, that you will
not find available in Hyperscale clouds.

If you choose a VMware Sovereign Cloud Provider, they can offer secure, shared
infrastructure and dedicated isolated private clouds. Both come with full
automated lifecycle management and can reduce cost dramatically, have a look at
the VCF TCO calculator to see for yourself.

Granted, regional cloud providers do not have economies of scale like public
cloud providers, but in terms of volume, many Sovereign Cloud partners have very
large Cloud estates. For example, OVH Cloud in France builds its own hardware
and has 100,000’s workloads running in its environments.

Lastly, specialized infrastructure and talent are where VMware Sovereign Cloud
partners excel; this is undoubtedly a good thing. Most VMware Cloud Providers
deliver managed services, which require operational skills in many different
areas, unlike Public Cloud vendors who do not. VMware Cloud Providers,
especially Sovereign partners, can help you on your cloud journey, skilled and
resourced appropriately to support your business, not just be an infrastructure
endpoint.

Innovation

Sovereign Cloud solutions may have a different level of innovation and feature
development than traditional cloud offerings, limiting their ability to keep
pace with evolving business needs and technology trends.

VMware doesn’t just mean vSphere. VMware’s portfolio of solutions is extensive
in capabilities and supports workloads, apps, containers, and data science
solutions. VMware Sovereign Clouds must be innovative, most governments and
industry verticals have vital requirements to get ahead of the pack, and
innovation is mandated in their cloud.

Thinking about this differently, public clouds, to be resident, must limit their
portfolios to only those that can be resident, separated from SaaS control
planes, and this limits innovation. VMware has always offered disconnected
solutions; everything runs in the region, in jurisdiction already, so you are
automatically gaining control of your cloud.

Innovation can be seen in 1 or 2 ways; that which is out of the box (SaaS and
PaaS) and that which must be built using new infrastructure and services.  An
out-of-the-box solution, such as an industrialized cloud solution, could be
great to get going quickly. Still, it is potentially a considerable concern for
compliance and security. Whereas building a solution to meet your needs offers
the opportunity to consider compliance and security from the get-go (which
should be a best practice). With data compliance, regulation and governance of
data privacy and industrialized data still evolving, it is better to innovate
and involve all lines of business to build the right solution. VMware Sovereign
Cloud providers offer GPU, AI, ML, Kubernetes, App marketplaces, secure app
portfolios, integrated pipeline solutions, and much more to ensure your needs to
innovate are covered but, most importantly, secure.

Overall, a VMware Sovereign Cloud can provide greater control, security, and
flexibility for governments and verticalized organizations that require unique
or specialized cloud computing services. Many Sovereign Cloud partners are
multi-cloud brokers, promoting the “right cloud for the application” aligned to
data classification and security requirements. They can be a one-stop shop for
customers who need multiple clouds and hybrid operating models. Get Cloud piece
