Cloud ArchitectureComparison Guide:Which Approach Is Right For You?

Find out the relative costs and advantages of these different cloud infrastructure approaches.

Traditional 3-tier

A platform where compute,

storage and networking

components are

independent and

loosely integrated.

Hyperconverged Infrastructure

A software-defined

approach to infrastructure

based on general-purpose

hardware tightly-integrated

with software.

Public Cloud

Cloud services running on

a shared hardware and

software infrastructure

owned and managed by a

third-party.

VMwareCloud

A VMware-managed

Software Defined Data

Center (SDDC) delivered

as-a-service via public

cloud providers or

VMware Cloud Provider

Program partners.

Easy to modify forspecific requirements

Possible to replace and modify individual tiers

Fine-tuned to unique application requirements

High upfront costs

Environment needs to be upgraded regularly

Limited integration, automation and management capabilities

Automated, simplified and rapid setup

Integrated management of servers from a single pane

Simplified IaaS deployment and operations similar to a public cloud

Difficulty catering for workloads with specific compute needs

Needs compute versus storage sizing

Avoid initial costs by shifting from CapEx to OpEx model

Added value of cloud-native services

On-demand capacitywith consumption-based economics

Significant time, effort and cost in refactoring apps for public cloud

Specific apps may needto comply with data residency requirements

No portability of apps to other infrastructure

No need for application rework or refactoring

No IT retraining required

Faster and seamless workload migration

Easy deployment

Doesn’t scale in as fine-grain incrementsas public cloud

Specific apps may need to comply with data residency requirements
