Item Portfolio

The task was complicated as i had to deal with data loss and partition damaged , on top of crashed vms. i had to mount images in live iso, to extract the data , and rebuild the entire vms that crashed again.

Crashed VMware vms

the client had problems with a mikrotik router, and ESXI server and a vm behind a vSwitch which was suppose to connect on TenGbp/s network. Then the second request was to limit the port on 4Gbp/s , particularly the interface that connected on ESXI server.

fix routes in mikrotik

Client had an infrastructure of Gaming servers behind the Mikrotik which was having issues from being DdoS every second with huge amount of packages above 10gbp/s. Normal firewalling would lead the mikrotik to reboot , since it was consuming way too much CPU. need to reimplement everything on prerouting / RAW and Mangle to have the mikrotik respond the expected way

Block DDos on Mikrotik

The client requested a new server to be build , in order to handle his high traffic website.
several components were involved into the project :
-Varnish cash
-Redis Server
-Percona Clusters
-frontend magento

services were split in several machines in order to optimize the performance

Magento2 Upgrade Server Infrastructure

The project request were:
1) installation of VestaCP and configure the panel
2) secure the server
3) migrate all the site over to the new dedicated server
4)create FTP, SFTP, accounts for each site (based on the clients needs)
5) configure the new A Records of the DNS

Installation of VestaCP and migration of all site
