Linux bonding meets sysfs

(sau ce te faci cand CONFIG_BONDING=y)

Petru Ratiu – aprilie 2011

The usual way

● modprobe bonding mode=1 miimon=100
● alias bond0 bonding
options bond0 mode=active-failover miimon=100

The “OMG it's buit in!” way

echo “ +bond0” > /sys/class/net/bonding_masters
echo "active-backup" >
/sys/class/net/bond0/bonding/mode
echo “ 100” > /sys/class/net/bond0/bonding/mode

The “let's pretend we don't have
ifenslave” bonus slide

ifconfig bond0 up
echo “ +eth0” >
/sys/class/net/bond0/bonding/slaves
echo “ +eth1” >
/sys/class/net/bond0/bonding/slaves

But why?
● Interfete multiple
● Reconfigurari fara reboot
● Probleme la modprobe -o bond0
● Distributii fara scripturi gata facute ;)

Collecting & Temporal Analysis of Behavioral Web Data - Tales From The Inside

Join me in this session where I'll share our journey of building a fully serverless application that flawlessly managed check-ins for an event with a staggering 80 thousand registrations. We'll dive into three key strategies that made this possible. Firstly, by harnessing DynamoDB global tables, we ensured global service availability and data replication across regions, boosting performance and disaster recovery. Next, we'll explore how we seamlessly integrated real-time updates into the app using Appsync subscriptions, making the experience dynamic and engaging for users. Finally, I'll discuss how provisioned concurrency not only improved performance but also kept costs in check, highlighting the cost-effectiveness of serverless architectures. Through these strategies and the inherent scalability of serverless technology, our application effortlessly handled massive user loads without manual intervention. This session is a real world example to the power and efficiency of modern cloud-based solutions in enabling seamless scalability and robust performance with Serverless
