Achievements
● I was tasked to management of an infrastructure which was stale since it's
inception. Nothing was updated, automated or even monitored.
Additionally no consideration was done regarding any future growth.
● My mission was to immediately implement monitoring and access control,
while also upgrading existing systems and installing new servers. ie:
Virtualization (implemented), Firewall (upgraded), VPN (upgraded), File
Sharing (upgraded), Domain (implemented/updated), Anti-virus
(implemented), Problem Management (Implemented).
● Not to mention a major network upgrade so it would be able to handle
more bandwidth and new services like VoIP and remote location access.
● I kept the lines open with other administrators from the remote locations,
with vendors and major carriers, looking for solutions and researching
new technologies to assist on my troublesome spots.
● Most of my issues on this engagement were related to unreliable
connectivity between locations, mostly due to the low quality of the links
and lack or redundancy.
● After implementing secondary connections, updating the routers and
firewalls, a load-balancing policy was implemented, which would keep
connectivity available even when one of the lines went down. That was a
major breakthrough which caused a huge improvement of service
reducing significantly downtime of any service to levels near by zero.
