how to estimate HW spec for serveral edge components on the same node

[oyamatakuro]

I would like to know how to estimate HW spec such as CPU, RAM and hard disk space in the case where serveral edge components are installed on the same node.

For example, in the case of standalone installation (2-host), Management Server, ZooKeeper, Cassandra, OpenLDAP, Edge UI, Router, Message Process are installed on a single host.

In the above case, the HW spec required to the host is the sum of required spec for each component which are described on

http://docs.apigee.com/private-cloud/latest/installation-requirements ?

Or can we just adopt the biggest one among the components as the HW spec required to the host?

Thanks,

Takuro,

Hardware specifications are driven by 1) TPS requirements, 2) minimum, recommended specs, driven by some components such as Message Processors and Cassandra, 3) CPU and RAM utilization % applicable to the company operational procedures, etc.

In the case of a all-in-one (aio) installation, this type of installation is consider a PoC/demo installation. Assuming the intended usage is PoC/demo, 8 cores 16 GB 500 GB disk should be more than sufficient.

If you are planning to use aio for any other purpose, we recommend considering a topology design that offers better resiliency and availability (4+ nodes).

Thank you for your answer.

I understand that the required hardware specifications are dependent on 1) - 3) you mentioned.

Then, for which installation topology and TPS are the minimum specifcations for each component described in http://docs.apigee.com/private-cloud/latest/installation-requirements?

In the case of 12 host clustered installation on http://docs.apigee.com/private-cloud/latest/installation-topologies

, the minimum required hardware specificaion for the node1 is the required spec for Cassandra + the required spec for Other (OpenLDAP, UI, Management Server)?

The hardware specification on the official documentation correspond to the components listed on the tables.

In the case of small topologies such as 5 nodes. These topologies are not, in most cases, (depending on TPS, availability, resiliency and other requirements) used in production. But they could assuming that they requirements allow it.

On a 5 nodes topology node 1 contains Cassandra, Zookeeper, UI, Management Server and Open LDAP. For that node, under the conditions mentioned above, the recommendation is to use Cassandra hardware spec recommendation: 8 Cores, 16 GB RAM.

Thanks for the info.

But looks like I cannot see the link due to my permission denied
