The document discusses the advantages and challenges of public cloud adoption, particularly for database instances, while emphasizing the continued relevance of on-premises systems. Migrating to the cloud can be complex, leading many organizations to adopt a hybrid environment that combines both cloud and on-premises infrastructures. Effective management tools for hybrid cloud setups can enhance operational efficiency and cost-effectiveness.

PUBLIC CLOUD USES & LIMITATIONS
The cloud is an attractive option for applications like database instances, but there are also many reasons to keep
systems on-premises for the time being. Furthermore, migrating to the cloud isn’t always a straightforward process, so it
can be time-consuming. As a result, many organizations end up with a hybrid environment in which some systems are in
the cloud, while others remain on-premises. The biggest problem with this architecture is managing it, as many tools can
only focus on the cloud or on-premises infrastructure. Tools that work in the hybrid cloud can thus save users time and
money.

CLOUD OPTION
• Attractive option for database
instances
• Cloud migration now common
• Also many reasons to stay
on-premises for now

LIFT AND SHIFT APPROACH
• Move workloads with little or no change to their underlying code
• Virtualize on-premises infrastructure instead of designing cloud architecture
• Fastest path to cloud and often first approach
• Does not offer advantages of cloud-ready applications

LATENCY
• Some workflows have high message
transmission rate with minimum
delay
• All networks have some latency that
worsens with distance
• So, real-time applications poor
candidates for cloud migration
REGULATORY COMPLIANCE
REQUIREMENTS
• Data privacy & protection laws
becoming increasingly common
• Some regulatory certifications not
available for public clouds
• So, processes that use protected data
may not run in the cloud
• Hybrid cloud uses on-premises
infrastructure for compliance
COST
• Sometimes public cloud more
expensive than own infrastructure
• Labor costs may account for majority of
cloud migration cost
• Easy to write applications from scratch
to run in cloud
• Difficult to migrate legacy applications
from data centers
Common Reasons For
Staying On-Premises

HYBRID CLOUD
• Some systems in cloud while others remain on-premises
• Challenge is to manage this architecture
• Many tools only focus on cloud or on-premises infrastructure
TOOLS AND THEIR BENEFITS
• Can save users time and money
• Hybrid cloud tools improved greatly
• Reduced purchase and maintenance cost
• Mitigated learning curve

PUBLIC CLOUD SUMMARY
The latest cloud solutions are clearly taking aim at other approaches such as physical servers and
hyperconverged infrastructure. However, it will probably take years for the cloud to significantly impact the
established market for on-premises infrastructure, which is currently dominated by companies such as Cisco, Dell
and HPE.
Solid integration with virtualized infrastructure is the most likely means by which this process will occur. This
approach could consist of an on-premises as-a-service solution jointly engineered with a software-defined data
center application running on a dedicated bare-bones server. A cloud solution could then provision database
instances on this server, providing an integrated hybrid cloud with a unified control plane. This environment would
then have access to a cloud platform and its cloud-native services.
