CloudSigma Review (2021): Get All the Facts Before Signing Up

CloudSigma is just over a decade old, having been founded in 2009. Since then, it’s grown to employ dozens of people and make a name for itself.

It’s got some high-profile customers, with the most notable being the European Space Agency (Europe’s equivalent to NASA).

But does that mean CloudSigma is right for you?

Is it a hidden gem in the world of cloud solutions, or a company that hasn’t become more famous because of hidden problems?

I’ll answer those questions for you, and more, right now.

Let’s start off by looking at the good things about CloudSigma.

CloudSigma Review: Pros

Pro #1: Great performance

Here’s the great thing about CloudSigma:

It guarantees 100% uptime.

Not 99% uptime, or 99.9% uptime, which is common on many hosting plans (especially shared web hosting).

Because CloudSigma is all about the cloud ONLY, it goes straight for perfect uptime. But here’s the OTHER great thing about CloudSigma:

It guarantees a certain network latency.

cloudsigma-performance-latency guarantee

In short, while uptime guarantees are fairly common among hosts, CloudSigma guarantees that AND a bare minimum of speed, which is more unique.

Does CloudSigma actually meet its performance guarantees?

As far as I can tell, it definitely DOES.

But even if CloudSigma fails to meet its uptime or latency guarantees, customers can get credits to their account.

So all in all, CloudSigma definitely offers the top-tier performance that it advertises. Considering its client list, that may not be so surprising.

Pro #2: Simple and flexible pricing

I think we can let CloudSigma explain itself here:

Our billing looks at total CPU, RAM, storage and data traffic usage every five minutes. You can purchase on demand via subscription or a combination of the two. It’s that simple.”

Prices vary across locations, but they’ll look roughly like this:

cloudsigma pricing

So you’d basically pay the rate of 1 CPU core above, the rate of 1GB of RAM noted above, etc, with your total bill reflecting how much of each resource you used.

This is even more specific and variable than the other common model of cloud pricing, which is a specified package that includes together RAM, storage, CPU, and bandwidth at a SINGLE hourly rate.

Even that form of pricing is flexible, so differentiating among the different resources as CloudSigma does may seem more complicated at first, but it lets you pay only for what you use.

Plus, as you may have noticed, all accounts get 1GB of RAM, 50GB of SSD, and 5TB of bandwidth (data transfer) a month, free.

As for the actual billing method:

CloudSigma has two billing methods available. This may seem complicated at first, if you’re not familiar, but it’s actually quite handy.

The first is a subscription model. It’s what you’re used to: you pay upfront and get a certain amount of resources for it.

The second is the “burst” model: you pay as you go, per what you use.

You can purchase subscriptions for more than one resource, which makes it quite customizable. And, the burst and subscription models are sort of automatically combined:

If you exceed the resources in your subscription, you’ll be charged for them via the burst model.

Enough with the explanations. Let me just show you an example of why CloudSigma’s pricing is good.

CloudSigma offers a billing calculator that lets you easily see the breakdowns of your cost, so using that:


The total cost of this hypothetical package is JUST $4.32 for the month.

Why? Because as I said, 50GB of storage is included for free anyway, as is 5TB of bandwidth and 1GB of RAM. So I’m only paying for the CPU here.

Now, suppose I go over these included free resources:


Increasing my RAM, storage, and bandwidth (a little bit), my total monthly cost is now much greater.

BUT, that’s because this assumes the monthly subscription model.

If I set the billing method to “burst,” (for one hour), this is all I’m dealing with:


Just $0.65.

So as you can see, this is an incredibly flexible pricing system, a step above the already-flexible models that many cloud providers offer.

And as far as the prices themselves go…they’re pretty good, too. For example, adding 1GB of storage costs just an additional $0.10 on a monthly subscription.

Pro #3: A wide range of resources is available

While few people reading this will likely need to use the max number of resources possible, it’s always good to know you have the option to grow with a cloud provider.

Now, keep in mind the resources you get for free—for full effect of the range:

1GB of RAM, up to 50GB of storage, and 5 TB of bandwidth.

Now, let’s assume you’re ready to scale up. These are the max figures per server:

  • Up to 40 CPU cores
  • Up to 128 GB of RAM
  • Up to 5 TB of SSD storage, and up to 1000 TB of Magnetic storage

With upper limits like that, it’s no surprise that CloudSigma can count the European Space Agency among its clients.

On that note, CloudSigma offers basically the full range of cloud infrastructure:

cloudsigma-infrastructure range

What’s more, CloudSigma offers customers the ability to mix and match.

For example, you could double-down on just dedicated servers. But you could also have a hybrid cloud that mixed in-house private servers with the price flexibility of the public cloud.

Not to mention dedicated resources within a public cloud framework, etc.

But don’t forget the more accessible products:

CloudSigma’s range of resources means it can service a range of business sizes. You don’t need to be a space agency, in other words.

Pro #4: Great on security (and transparent)

CloudSigma can boast an array of privacy and security certifications:


The most attention-worthy things here are the “ISO” certifications.

ISO stands for “International Organization for Standardization,” and as the name implies, it’s an international body for setting quality standards in a variety of industries.

ISO is recognized by the UN and has been around since 1947, so the ISO certifications that CloudSigma has carry some weight.

These certifications cover a range of security issues: they cover CloudSigma’s physical security, it’s digital security, etc.

If you want a more detailed explanation:


CloudSigma also lists the specifications for the specific data centers in each location it offers.

Additionally, as CloudSigma is headquartered in Switzerland and offers Swiss servers, you have the option of spinning up your cloud instances from Switzerland.

Switzerland is rightly famous for its privacy laws and privacy-focused institutions, so while it may not be as fast as generating a cloud server from a location closer to you, it’s great for improving your security:

cloudsigma-security-swiss location

And lastly, on the note of data privacy, you can check out this blog post in which CloudSigma vows to fight for its customers’ privacy, turning down requests for information from law enforcement and even a willingness to go to court.

So overall? Most reputable cloud providers appear to have decent infrastructure, but CloudSigma goes out of its way:

It offers great security and privacy practices, AND also is super transparent about all of it.

Pro #5: Multiple locations available AND international-friendly website

There’s no need to dilly-dally. Here’s the list of locations CloudSigma offers at the time of this writing:


If I’m being honest, I’ve seen cloud providers offer more locations than this. So I don’t think it’s a crazy offering.

But, it’s still good nonetheless. And CloudSigma is continually adding to its list of locations—so don’t worry if one close to you isn’t available yet.

Aside from just offering data centers in many locations, CloudSigma also makes sure its website is friendly to international traffic.

For instance, users can calculate the price of their cloud instance in their native currencies, and check out in them as well:


Plus, CloudSigma even offers its site in multiple languages:


Sure, it’s not every language or every currency, but it’s more than what I see on most competitors’ sites.

Pro #6: Support representatives are solid

Though not the best ever, getting customer support through representatives is pretty reliable with CloudSigma.

Take this live chat as an example:


The rep may not have noticed that I had already asked my question, so I reiterated it (he was typing a response at points, so perhaps he was working on a reply anyway).

He replied a few minutes after I asked again:


I found that the rep took a little longer to respond than reps on other live chats.

However, it seemed that the responses were more genuine than what reps on a competing service would offer—so the wait times aren’t a bad thing in this case.

In other words, I waited marginally longer to get an answer, but the rep used the time to be informed and respond well. This has been the case in other tests I’ve done of CloudSigma’s support.

So while it may not look like a strong live chat from the outset, I’ve found that it’s overall speedy and reliable.

You can also contact reps through email for more detailed queries.

CloudSigma Review: Cons

Con #1: Not the best for ease of use

IF you ALREADY know what you’re doing—if you’ve used cloud providers several times before, are a developer, or generally comfortable with this stuff—then CloudSigma is user-friendly.

But if you’re not as familiar with cloud hosting, then CloudSigma isn’t the easiest provider to work with.

Don’t get me wrong, it’s not a lost cause. But in general, CloudSigma is geared towards a more cloud-proficient audience.

Here’s a good example of what I’m talking about. These are some of the cloud integrations CloudSigma highlights:

cloudsigma-cloud integrations

If you know what you’re doing, most of these are going to be helpful in making the cloud easier to use and giving you more tools to manage your hosting.

But if you’re a newcomer, these aren’t really the integrations that will appeal to you.

A rival focusing more on ease-of-use would highlight integrations like content management systems (WordPress, Drupal, etc) or control panels (like cPanel or Plesk), for example.

CloudSigma offers its own native control panel with helpful features, to help users manage their cloud:

cloudsigma-ease of use-api

But to be honest, even this API is most useful for already advanced users.

Additionally, while it’s good that plans are highly customizable, there’s not a whole lot to guide newer users through what they should select for their cloud instances.

Even the onsite knowledge side of customer support—despite being good overall—carries some of these flaws. So on that note:

Con #2: Support material not always beginner friendly

By support material, I mean the informational resources readily available on the website, for customers to peruse at their own convenience—as opposed to ways of contacting service representatives.

On CloudSigma, this mostly takes the form of a “community” page. The community page features a small forum, as you’d expect, but also has tutorials and FAQs.

Some of the FAQs address more basic questions:


But generally, the simpler questions and answers are about billing. It’s still useful, and can address questions more confused customers have.

Unfortunately, as most of those simpler FAQ articles are about billing, there’s not much to cover the technical side of things.

For the technical side of things, there’s the tutorials page.

But take a look at some of these highlighted tutorials, and tell me how many of them are going to be useful to a beginner?



To reiterate: I am NOT saying these tutorials are bad. They’re great for non-experts who are still generally proficient and tech-savvy.

But it just goes to show that people who are newer to cloud hosting won’t receive as much support for the necessary learning curve.

Con #3: Could be more intuitive to install operating systems

This is related to the ease of use point, but it’s a more important part of cloud hosting.

Basically, CloudSigma does have tools for setting up a given OS on your server.

You can add Windows licenses to your package, for example:

cloudsigma-operating system2

And overall CloudSigma is certainly flexible enough to allow more advanced users to easily set up whatever their preferred operating system is.

However, other cloud providers make this easier: they usually offer easy installations of a variety of Linux distributions as well as versions of Windows.

Typically, in these situations, a customer doesn’t have to do all that much aside from choosing an OS, clicking an “install” button, and then doing basic setup within that OS.

But here’s an example of what setting up a Linux distribution looks like in CloudSigma.

Suppose you want to install Ubuntu, a super popular Linux operating system:

cloudsigma-install operating system

You’d need to find the right version in CloudSigma’s library (above), clone it, enter in some commands to set up a password and users and administrative privileges, etc—then you can use it.

It’s not the most complicated thing in the world, but there’s much more room for error for less knowledgeable users.

Plus, as I’ve mentioned, the guides and support don’t do much to help confused customers figure out this process.

CloudSigma Review: Do we recommend CloudSigma?

So, moment of truth: is CloudSigma right for you?

If you’re looking into cloud hosting for the first time, CloudSigma isn’t the best option.

There will be a steep learning curve, and it’d be harder for you to take full advantage of CloudSigma’s power and customization.

But if you’re familiar with cloud hosting, even if you’re not an expert, then CloudSigma is certainly worth trying.

With a very flexible pricing system and generally good prices to go with it, plus flexibility in choosing the nature of your cloud products, it’s easy to see how CloudSigma stands out.

Not to mention, solid security and a very transparent approach to the business.

But hey—if you’re not sure, just try it without risk!
