LAN and WAN
Managing DHCP, DNS, FTP, SFTP, HTTP,& HTTPS
Enterprise Integration Patterns
Essential Technology and skills:
IBM WebSphere and IBM MQ (We are negotiable to candidates with at least 4 years on these tools).
TIBCO and Oracle Integration tools are not relevant for our area. However, we’re negotiable who have a combination IBM tech and others.
Linux and Windows Systems Admin Support
Custom scripting experience (i.e.,Powershell, Bash, Python etc.)
This is to automate processes within the Operating Systems
Infrastructure Security – Active Directory, Firewalling, Permissions and Certificates etc.

84-minute brownout and eight-hour VPN vanishment caused by update that left systems unable to access config files Share

Google has explained how it took a big slab of its Euro-cloud offline last week, and as usual the problem was of its own making.
The 9 December incident was brief and contained – it started at 18:31 PT (02:31 UTC), lasted 84 minutes and only impacted the europe-west2-a zone – but meant 60 per cent of VMs in the zone were unreachable from the outside world.
Google said VM creation and deletion operations stalled during the outage, while any VMs or hosts that had hardware or other faults during the outage were not repaired and restarted onto healthy hosts.
Thread-Per-Core Buffer Management for a modern Kafka-API storage system
Superscalar CPUs with wide GB/s memory, NVMe access times in the order of 10-100’s of microseconds, necessitates a new buffer management for low latency storage systems.

As I have previously observed, software does not run on category theory, it runs on superscalar CPUs with wide, multi-channel GB/s memory units and NVMe SSD access times in the order of 10-100’s of microseconds. The reason some software written a decade ago - on a different hardware platform - feels slow is because it fails to exploit the advances in modern hardware.
