FAQ - Zesty Disk for standalone instances

If you have already integrated your AWS account with Zesty, and you want to update the IAM permissions, use the procedure described in Integrate your AWS account with Zesty .

After modifying volume parameters, there are wait times imposed before making further modifications, When you modify with AWS, AWS limits further volume modifications - including extension - for at least 6 hours. This imposes a risk of running out ...

Yes, you can limit the maximum filesystem size by configuring a Zesty Disk policy and attach that policy to your instances. For more information, see Configure Zesty Disk .

After implementing Zesty Disk, auto scaling typically results in a measurable increase in IOPS. There is no negative impact on the instance or application when using Zesty Disk.

The Zesty Disk machine learning learns your usage patterns and, based on these trends, determines how much additional storage capacity is needed. Typically, the first extension is about 10-15% of the original filesystem size, though this will be hi...

The filesystem efficiency score is the filesystem utilization including the extra capacity required for Zesty Disk management. The percentage is the highest of the past 72 hours, where 100% is perfect. When it comes to rightsizing filesystem spac...

Zesty collects only the metadata specified by the IAM role needed to connect your organization to the Zesty platform . If you disconnect from the Zesty platform at any point, whether at the POC or post-activation stage, Zesty does not mainta...

The Zesty machine learning system builds a model of your filesystem usage and trends based on information sent by the Zesty Disk agent. The system uses this information to set thresholds for minimum and maximum size, minimum buffer, and more. When ...

No downtime is required for the extending or shrinking. When extending, a new volume is attached to the filesystem that can be used immediately. When shrinking, the data is redistributed onto other volumes with available space before the surplus v...

EZswitch migrates the data using a “copy-on-write” mechanism. After the first reboot, all new data is written to the Zesty Disk, while existing data is copied to the Zesty Disk in the background. After the second reboot, the Zesty Disk mount poin...

When using a single EBS, your application performance is limited by the EBS settings, such as 125MB/s and 3000 IOPS. In contrast, Zesty Disk combines multiple EBS volumes (typically 3-5 in a steady state), thus increasing performance by a factor of ...

Regardless of the size of the data to be migrated, the Zesty Disk filesystem starts small and scales up as data is transferred to it. The data migration occurs in parallel with the application’s workload, so the duration depends on the intensity of ...

Yes, sure! See Integrating Okta SSO with Zesty

You can manage Zesty Disk with Terraform, as described in https://github.com/zesty-co/terraform-zesty-disk-config/tree/master

The quickest way to boost performance and save costs is to use EZswitch to migrate existing filesystems and to build new instances with Zesty Disk as the default volume. Zesty is happy to assist with configuring this in your environment.

Zesty Disk can handle applications of any scale, without any performance degradation. We support Kafka, EMR, Elasticsearch, Apache Solr, and other mission-critical applications. Typically, there are about 3-5 volumes associated with Zesty Disk. Duri...

Zesty Disk doesn’t add any constraints. Scalability is constrained only by the number of volumes that can be attached to an instance, which can be 27 volumes or more, depending on the instance type. In addition, Zesty Disk can support a few PB of da...

Just like with EBS, rate limiting can only occur if the maximum IOPS or throughput configured on the volumes associated with Zesty Disk is reached. Zesty Disk lets you change IOPS or throughput configuration within AWS EBS limitations.

You can monitor Zesty Disk just like any other filesystem you currently use. The Zesty Agent can also be monitored via a dedicated file that logs a "heartbeat" with each run. For other monitoring requests, contact Customer Support.

Zesty Disk can integrate with Slack. You can configure email alerts for receiving notifications from Zesty.
