Setup Cost

Zadara offers predictable pay-per-use pricing, with all-inclusive features and support, appealing to cost-conscious enterprise buyers.
It operates on a pay-as-you-go model, meaning if a machine is used for only an hour, the pricing will be calculated for that hour only, not the entire month.

In some projects, incorrect decisions were made by not consulting them first, resulting in higher setup and maintenance costs.
Scrum Master/ Agile Coach at Porch Group

Senior Analyst - Data Engineer at a tech vendor with 10,001+ employees
The best feature I appreciate about Amazon EC2 Auto Scaling is its health check functionality; when a server becomes unreachable or enters an unhealthy state, it automatically triggers an alert, and the load balancer responds by spinning up a new server, ensuring that traffic is distributed effectively.
Senior AWS Consultant at Quantum Integrators
This pre-configuration makes on-demand scaling refined, and the configuration includes automatic traffic distribution because when the first system is overloaded, new incoming traffic is redirected to the newly created systems.
Scrum Master/ Agile Coach at Porch Group
Zadara's troubleshooting feature is very valuable for me.
IT Technical Architect at AVALIS
The most valuable feature is its storage management capability.

Featured Reviews

Karthikeyan Ganesan - PeerSpot reviewer
Scrum Master/ Agile Coach at Porch Group
Offers automatic scaling features but can improve user interface and setup guidance
Customizable policies help us determine how scaling should occur. In enterprise environments such as healthcare or banking with numerous instances running different applications, customizable policies allow appropriate scaling. For critical servers, we can set up a higher number of new instances to scale out to prevent downtime. For less critical servers that perform simple tasks such as file copying, we can use customizable policies to scale out minimal instances to avoid unnecessary expenses or cloud costs. Regarding integration, there are some disadvantages in AWS where certain availability zones or regions experience glitches. This can cause production halts because of problems on Amazon's side. In particular regions, when integrating Amazon EC2 Auto Scaling or other services, there might be delays in creating new Amazon EC2 instances, sometimes becoming inefficient.
