Offers customization and flexibility with great support
Scalability depends on whether the client wants to scale up or scale down. It decreases resources based on demand. The great aspect of scalability is the flexibility to allow business success to optimize resource solutions and cost efficiency. Another crucial aspect of scalability is auto-scaling. When you have the opportunity to auto-scale, it can't always be available for everything. If you have chosen to integrate with auto-scaling, it's marvellous and doesn't require additional effort. Auto-scaling gives you the edge by using the capacity you have efficiently, scaling up or down as needed. These flexibilities within the EC2 feature instances of AWS play a crucial role in helping me utilize AWS EC2 Intelligent efficiently.

Enhancing storage management efficiency with user-friendly experience
Our customers are using Zadara for their research and development environments. We provide infrastructure for government projects, but we are often not fully aware of their specific usage.  I typically use it for our infrastructure and offer both Zadara and Microsoft Azure to our customers Zadara…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"An advantage of Amazon is that it offers a wide range of infrastructure services with an easy way to configure them."
"Amazon EC2's flexibility and ease of configuration were found to be very valuable."
"Amazon EC2's most valuable feature I have heard from clients is easy provisioning. Provisioning is very quick and easy."
"The ability to quickly spin up instances on demand with zero upfront costs or infrastructure is the most valuable for me."
"I use it for NextCloud and for developer purposes."
"Amazon EC2 is really reliable and provides great flexibility."
"I like the AMI-related features. A very good feature of this solution is the customizable AMI. It is a very good feature provided by Amazon. The encryption technologies are also very good. We are using KMS, etc."
"EC2 is flexible when we need to increase its resources (memory, boosting, and storage) based on our usage. That is the power of EC2."
"One of the most useful features is that they provide iSCSI as a service."
"It provides very satisfactory storage performance."
"Zadara is a fully-fledged platform, and our customers are happy with its use."
"One of the most valuable features is its integration with other cloud solutions. We have a presence within Amazon EC2 and we leverage compute instances in there. Being able to integrate with compute, both locally within Zadara, as well as with other cloud vendors such as Amazon, is very helpful, while also being able to maintain extremely low latency between those connections."
"The most valuable feature of Zadara is its ease of use and safety. Overall the solution is a complete package, it has all the features needed."
"I find Zadara's user-friendliness from both the customer and engineering perspectives highly appreciated."
"The processing is much faster with this product."
"The most valuable feature is the flexibility in terms of deployment options."
 

Cons

"Current inability to change the resource service levels."
"The price could be better, and it could be more affordable. Because I run my own servers, the prices are quite high."
"The only issue with EC2 is that it makes it difficult to install an LLS certificate on your WordPress website that you have deployed inside that virtual machine. That becomes complicated."
"The monitoring part could be improved. When we're building and configuring things or doing database replication, EC2's monitoring could provide more information. It's hard to find the information I need in the graphs they provide."
"We're expecting to have Graviton instances. Graviton means it's not internal, it's a low-cost instance. At present time, Graviton is not supported for a few packages."
"The initial deployment was complex."
"Amazon EC2 is very expensive, and it would be helpful if they decreased the pricing."
"The scalability could improve."
"Having iSCSI over the internet using a VPN, the IPSec tunnel is really the only thing that I find missing from this product."
"There are still some storage features that they lack. For example, other vendors implemented the auto-tiering feature a long time ago, while Zadara Storage Cloud is just coming out with this feature today. So, they are a little bit late compared to the market."
"There is room for improvement in pricing as it is currently quite expensive."
"The initial installation was difficult because many steps required the command line interface (CLI). Maintenance can also be complicated, especially when deeper troubleshooting requires navigating the CLI and searching for logs."
"Some of the features are a little bit slow to come to market."
"In the next release, there can be some improvements to the web console by adding more features because the console is simple. Additionally, the calculator could improve."
"I would like to see them be a little bit more proactive in terms of the patches and updates that are available. I would like to see more disclosure and information around what fixes or what enhancements are available within a patch, and help in coordinating and scheduling that. Right now, it's driven more by the customer in reaching out via a support ticket."
"The range of support of VMware could be better. It can support Windows, however, it cannot support other operating systems like IBM AIX. This needs to improve."
 

Pricing and Cost Advice

"I use the free tier, although I have paid for some services that are not free. The overall cost of this solution depends on the services you use."
"It has helped to reduce costs with infrastructure."
"EC2 pricing is somewhat transparent, in that AWS provides pricing for all instance types. However, the number of pricing options can be confusing."
"Amazon EC2 is a very expensive solution."
"The licensing of Amazon EC2 is expensive. Microsoft Windows Servers are expensive to license."
"The tool's pricing is not cheap."
"There is a license required to use this solution and we pay on a monthly basis."
"It's expensive, and it could be cheaper."
"One of the factors that ruled out several providers was cost. They were way too expensive for the volume of data that we needed and the speed at which we needed to be able to manage it. There aren't a lot of providers that can do that."
"The pricing is very competitive and the fact that they have very compelling discounts for multi-year commitments is great."
"It is a nice licensing model and it makes it quite simple because we just pay for what we use, and the bill that comes shows us exactly what customers are using what resources."
"The price of Zadara is very good and it covers everything. There is no subscription needed."
"The pricing and licensing are very simple and the cost is predictable, although, like everything that you pay for as you use, you have to be mindful of what you're using."
"If you just take the street price of Zadara Storage Cloud and look up the price or cost per hour, then you could think that Zadara Storage Cloud is extremely expensive or a solution only for enterprise use. That is not true. You need to compare the entire system. This means that you don't stop looking at just the street price, but you need to consider all the features, requirements, and costs of support as well as the extra cost that other vendors have. Other players just play with hidden, additional costs. Everything is included in Zadara Storage Cloud's licensing cost; what you get is what you pay for."
"For our use, it's appropriately priced and overall, it's proved to be very cost-effective against other tier-one vendors."
