Cloud Infrastructure as a Service (IaaS) is revolutionizing how IT departments design and run critical business applications. But there’s not a single model for success. While navigating the market, you’ll encounter many different ways to architect, deploy, manage and pay for your cloud infrastructure. Each has distinct advantages and disadvantages, providing you varying degrees of control, scalability, performance and security.
So how do you choose the right home for your applications? Take a tour through “Cloud Town” to find out.
Popular Public Cloud services — like Amazon Web Services (AWS) and Microsoft Azure — provide hyperscale, multi-tenant compute and storage resources over the internet using virtualization and a massive global data center presence.
Low entry prices and limitless scalability are a huge boon to app developers.
Like all hosted services, you don’t own public cloud infrastructure — you rent it, or reserve the resources, kind of like you would at a hotel room or high-rise apartment.
Residents in these buildings don’t have to worry about building upkeep, perimeter security and utilities.
Public Cloud platforms are powerful, but they can be pretty intimidating (or time consuming) to figure out on your own. AWS, for instance, has roughly 70 products and services and introduces dozens of new features each year.
While easy to get started, it’s even easier to make a wrong turn.

The beauty of Public Cloud lies in its ease of access, pay-as-you-consume model, and ability to scale on-demand.
Potential downsides, however, include high costs of auxiliary services, noisy neighbors and lack of infrastructure control and customization.Let’s take a peek inside . . .
Public Clouds offer big discounts if you pay upfront for server resources for a specified period of time (called reserved instances).
When used right, this is a great deal!
But often times, users end up paying for resources they really don’t need.
Dedicated Private Clouds are single-tenant, fully isolated hosted environments. The environments are fully customizable and available at fixed costs based on application resource requirements.
Residents are isolated from their neighbors and can fully customize their space, making them popular destinations for individuals looking to protect valuable possessions.
Much like Public Cloud, residents share costs of important things like security, utilities and critical maintenance.
But before you decide one way or another, that’s not the only kind of hosted private cloud available . . .
From a performance standpoint, DPCs are every bit as powerful as the public cloud. But there are other reasons IT pros choose this model over hyperscale varieties.Let’s meet some of the residents . . .
Virtual Private Clouds (VPCs) are logically-isolated environments hosted within multitenant (or public cloud) infrastructure. Like DPCs, users pay on a monthly basis for a pool of resources capable of accommodating whatever their workloads demand.
In VPCs, the underlying infrastructure is shared, but akin to a townhouse, segmentation is used to ensure each cloud is secured and resources are never shared.
Cloud Environments — Public or Private — are a far cry from how most IT departments ran their businesses just 10-15 years ago, when On-Premise Data Centers powered most business applications.
That’s because it’s not the physical home that matters — it all comes down to the diverse needs of residents and families.
In fact, most denizens of the cloud won’t stay put in one environment . . .
Let’s make no mistake — some large enterprises and sophisticated IT teams still prefer managing their own data centers. That means they acquire the space, manage the utilities, purchase new hardware every three to five years, run security operations, troubleshoot downtime, and sometimes even set up secondary backup and recovery sites.
It's a major investment of time and resources, which is why on-prem-only organizations are increasingly rare.
The concept ‘multicloud’ is quickly becoming an apt descriptor for many modern IT strategies. It’s sort of like accommodating the needs of several generations of a family at once. Unless you’re in a 90s sitcom, not everyone’s going to fit under one roof. Different family members will live in different environments based on their varying needs — space requirements, lifestyle, proximity to work, ability and interest in taking of the property, etc.
And sometimes, a single application will need to traverse different clouds. This is called Hybrid Cloud.
Would you sign a lease on an apartment for a weekend getaway? Neither would this couple.
Shhhh! Multi-tenant residences mean sometimes your experience is degraded due to the behavior of those you share the space with.
High-rise and hotel living is nice, but doesn’t offer the freedom of DIY living like other options.
Danielle’s in-laws and extended family showed up out of the blue. They are not staying in her house . . . because lack of capacity, of course ;)
Ronak uses this building’s gym on an à la carte basis. He’d get a better rate if he joined, but he only needs it one day a week.
Residents of high-rises like this love that there is 24/7 security staff protecting their home.
Beware the fine print of this parking garage. You pay virtually nothing to get your vehicle in, but prices climb if you ever want to take it out.
This building doesn’t offer an ideal-sized unit for Deanna and her family. They end up settling for way too much space. Maybe they’ll need it someday?
Why does Kelly’s family rent a separate unit for every member of their family (plus dog)?
Bachelor Pedram rents a big apartment, but all that extra space is perfect for his frequent parties.
Michael & Wendy (and the dog) have exactly the right amount of house. Every room has its function, and they have just enough room left over to feel comfortable.
We’d show you Dr. James’s house, but he’s architected his home to keep his secrets safe.
Elaine & Earl moved to this DPC after years in the country. They wanted the familiarity of all their old stuff without the extra burden of maintaining the property. Oh yea, and they wanted a custom swimming pool. Nice perk!
This DPC is ideal for the predictable needs of the couple’s 24/7 routine. The former owner Pedram, however, recently moved to the Public Cloud District to accommodate his raucous, spontaneous lifestyle.
Building permits are a cinch in this DPC community. When the tactful planner Eugene needs to make an addition, he can do so on-demand.
Betsy’s landlord paid for her movers (plus an interior designer!) to make the transition efficient, pleasant and worry-free. Woot!
Ryan enjoys his new surroundsound at full blast. Don’t worry, he is the respectful type. He knows the sound is contained to the unit itself and doesn’t disturb his neighbors.
This idyllic on-prem manor looks nice on the outside, but a lot of work goes into keeping it so pristine . . . and sometimes it’s not so pristine at all.
