Hybrid Cloud vs Public Cloud vs Private Cloud

Hybrid Cloud vs Public Cloud vs Private Cloud

These days you have lots of options when looking where to host your systems.  Public Cloud, Private Cloud, and Hybrid Clouds are three options each offering their own distinct advantages.  While Public Cloud (AWS, Azure, Google Cloud, Alibaba Cloud and more) get all the buzz, many customers would actually be better off with either a private or hybrid cloud.  Public clouds are great for some use cases but cannot provide the optimal solution for all users and applications.  At 8CLOUD8 we focus on hybrid bare metal clouds customized to your needs to bring together the best of public cloud, private cloud, and hybrid clouds.  So why should you choose a Hybrid Bare Metal Cloud?

You Run Expensive Software (SQL Server, Oracle, SAP, etc)

Nothing can beat the performance per Core of a bare metal server customized for you.  With most enterprise software being billed by the Core, bare metal servers can save 75% or more just on licensing costs alone.  Add-in the savings of bare metal vs cloud solutions and the effective price to run expensive applications can be cut by 80+% by using bare metal.  Total Cost of Ownership (TCO) is significantly reduced as you still don’t manage the hardware, data center or network, but you do get the license savings from optimized server infrastructure.  One advantage with 8C8 vs many public clouds is that you can also bring your own license (BYOL), making sure you don’t pay for software twice.

You Don’t Have Facebook/Google/Twitter’s Budget for DevOps

With a Cloud-native software application and/or a skilled team of DevOps you could take advantage of PaaS solutions to reduce your TCO.  Most applications aren’t built for the cloud, and most organizations just don’t have the DevOps capacity necessary to take advantage of the cloud’s unique advantages.  Most users are still using the cloud for static VMs and paying 400%+ more than they should while experiencing lower reliability and poor support.

You Have Some Cloud Applications and/or Want to Migrate to the Cloud Over Time

A key advantage of a Hybrid Cloud vs a Private Cloud is that the Hybrid Cloud has low latency, high bandwidth connectivity to one or more Public Clouds.  Want to POC or test out the latest cloud service from AWS, Azure or others? Hybrid clouds let you do that.  You have some applications that don’t do well in the cloud, but need to connect to others that are in the cloud? Hybrid clouds can do that too.  With a Hybrid Cloud, you aren’t locked-in to any one cloud vendor but can still take advantage of each cloud’s unique solutions.

Some Applications are Migrated to Public Cloud but are Having Issues

You spent a great amount of time and expensive resources to migrate some systems to the cloud, but now you are experiencing exploding costs, performance and/or scaling issues, lack of control and poor support, or a combination of all the above.  We often see many issues with DBaaS solutions or just running enterprise DBMS on cloud VMs.  Bare metal hybrid servers can help you migrate pieces of an application or entire systems to a better performing, lower-cost options while keeping significant chunks in the public cloud.

Shared Servers Worry Your Security Team

While many public clouds take great strides to secure their infrastructure, security gaps are native to the shared nature of the public cloud.  Unfortunately, very little can be done about exploits on CPUs, firmware, or Hypervisors that can leave your VM vulnerable due to another user’s error.  Private clouds often mitigate much of this issue but also add complexity and other vulnerabilities due to the myriad of software needed to run a private cloud.

More Customization Options

While public clouds have hundreds of options, often many of them overlap and provide very few effective choices.  Many times, a user has to pay for more cores or memory than they want to get the right storage or network throughput.  Additionally, due to the nature of the cloud, most public clouds discourage you from using their fastest storage, local NVMe/SSD, because it gets deleted on shutdown.  8C8 Bare Metal Cloud Servers can be customized to your specs very quickly and you can be up and running in a few days, sometimes even hours.  Want a high performance 8 Core, 512GB RAM, 8x15TB NVMe server? Sure, we can do that.  Need ten 6 Core 64GB blazingly fast 4.8 GHz servers, we can do that too.  In many scenarios, bare metal is much more cost-effective than AWS, Azure, Google Cloud, and other clouds.

Your Workloads are Relatively Static

If you are just running VMs 24×7 in a public cloud, then you are likely wasting money.  The TCO for a cloud VM is about 4-5X higher than a Bare Metal Cloud Server.  Even shutting down a public cloud VM for 50% is still more expensive than running that same workload on a Bare Metal Cloud Server.

Your Applications Don’t Handle Failure Well

We have experienced the 30% VM failure rates, the constant PaaS blips and the nightmare support that entails from public cloud solutions.  Many times, the response from support is that the application has to be able to handle transient failures, and build out redundancy everywhere, often geo-redundancy.  Unfortunately, not only can many applications not handle those transient failures easily, it is incredibly expensive to duplicate every system.  Outside of public clouds, DR plans are for exceptions, not for routine operations.  With Bare Metal Servers our failure rates are below 3%.

PaaS Solutions aren’t Providing the ROI or reduced TCO You Were Hoping For

It seems like in technology every 10 years or so we go through a wave of outsourcing to Centers of Excellence.  PaaS solutions are another take on that concept, where cloud vendor X can run software Y much better than you and your capacity constrained team can.  In some cases that is true, in many cases, we have found it isn’t true.  Your team only has to worry about your specific use, while the cloud vendor has to worry about 1000s of customers with a near-infinite amount of use cases.  What often happens is flaky, continually patched and changing solutions that many times often cost you more of your team’s time than doing it yourself.

You Want to Minimize Risk By Using a Multi-Cloud or Multi-Vendor Strategy

With each cloud being proprietary and prone to its own various issues, many companies are electing to not just go with Geo-Redundancy, but also to go with a multi-cloud strategy to ensure they hit their SLAs.  A Hybrid Cloud can be a part of such a strategy with fully separate hardware, software, networking and data centers.

Containers, Containers, Containers

Virtualization has ruled servers for nearly 20 years, but now containers are quickly taking their place.  While containers can’t quite fully replace VMs today, they are getting there quickly.  Containers run better on bare metal.
