High availability
High availability is a characteristic of a system, which aims to ensure an agreed level of operational performance for a higher than normal period.
There are three principles of system design in high availability engineering:
Modernization has resulted in an increased reliance on these systems. For example, hospitals and data centers require high availability of their systems to perform routine daily activities. Availability refers to the ability of the user community to obtain a service or good, access the system, whether to submit new work, update or alter existing work, or collect the results of previous work. If a user cannot access the system, it is - from the users point of view - unavailable. Generally, the term downtime is used to refer to periods when a system is unavailable.

Nines (card game)
Nines is a trick-taking game played with a standard deck of 52 playing cards. Nines is played by three people, and the object is to lower your score from 9 to zero.
Rules of Nines
Dealing
All of the cards are dealt one at a time into four hands of thirteen cards. One hand is for each player, and the remaining hand is set aside as an extra hand that the players can pick up (Four players can play, but with no option to trade hands, and only three tricks required to 'book', or keep the same score).
The extra hand
After all the cards are dealt, each player can look at his hand and decide if he wants to trade it for the extra hand. The dealer has first choice of taking the hand, and then the choice moves to the left. Players to the left of the dealer may take the hand that someone else has already traded in if they so choose.
Playing
The object of game play is to take tricks. Trump goes in the following sequence: Clubs, Diamonds, Hearts, Spades, No Trump (the first four are alphabetical). In some circles, the game runs Hearts, Spades, Diamonds, Clubs, No Trump.

High Availability/Disaster Recovery (HA/DR) Basics
Welcome to ScienceLogic Symposium 2021. My name is Jesse Triplett. I'm a Senior Support Engineer with ScienceLogic Support, and in this video, we're going to cover the basics between HA and DR cluster. So let's get started. This video will be covering the basics of a heartbeat network, services and the resources that make them up, virtual IPs or VIPs and what the differences are between HA and DR clusters. In short, the heartbeat network is merely a network through which the primary and secondary nodes pass back and forth a token. Each node expects that token to come back around in a configured amount of time. If that token does not come back around, then the cluster will begin a a failover process. This is the top level cluster health check for your cluster. Services are made up of ...

Design Patterns for High Availability: What gets you 99.999% uptime?
In this video, we discuss the topic of availability in distributed systems. We categorize organizations based on their acceptable levels of availability, ranging from startups to mature companies aiming for five to six nines of availability. InterviewReady: https://interviewready.io/ We share a real-world example of a startup facing availability challenges with its database hosted in the wrong region. The solution involves migrating the database to a more suitable location and implementing a step-by-step process to minimize downtime. Here are five principles for building highly available systems: 1. Simplicity over Perfection 2. Downtime Over Loss 3. Lesser Moving Parts 4. Chaos Engineering 5. Incident Reports and Root Cause Analysis We also touch upon fault tolerance strategies suc...

Welcome to ScienceLogic Symposium 2021. My name is Jesse Triplett. I'm a Senior Support Engineer with ScienceLogic Support, and in this video, we're going to cover the basics between HA and DR cluster. So let's get started.
This video will be covering the basics of a heartbeat network, services and the resources that make them up, virtual IPs or VIPs and what the differences are between HA and DR clusters.
In short, the heartbeat network is merely a network through which the primary and secondary nodes pass back and forth a token. Each node expects that token to come back around in a configured amount of time. If that token does not come back around, then the cluster will begin a a failover process. This is the top level cluster health check for your cluster.
Services are made up of resources. These resources can be anything that an application needs to run. That includes mounted storage, file systems, the software for the application itself, really anything. For SL1, we specifically use distributed replicated block devices, a backend database made of MariaDB, the processes and parts of the application for SL1 itself, as well as a virtual IP. The VIP is a secondary IP that is applied to the public-facing primary NIC on the node that is currently running the SL1 stack. What this means is that any system that accesses that VIP is sure to get the SL1 stack itself and not the non-active node. It is, in that way, a very simple load balancer.
When it comes to HA versus DR, the easiest way to describe it is that HA is meant for and focuses on immediate and automated failover from one node to another. This means, if for some reason, one node cannot run the surface, the other note will pick up the slack. What makes DR, or disaster recovery clusters, different is that instead of focusing on server-level issues that would prevent a server from being able to run the application, such as a hypervisor failure, disaster recovery focuses more on less common, but more impactful, issues that may bring down an entire data center. For that reason, you have a primary node and a secondary node that is offsite in a separate data center.
Because of the distance between these two nodes and the latency between them, this means that in the case of a failure situation, some user intervention will be required. That is the difference you are most likely to notice between running an HA cluster and the DR cluster. It's also important to note that you can run an HA cluster with a DR node for maximum stability and uptime.
I hope this video made clear that the heartbeat is the primary cluster level health check of the nodes themselves, that highly available services are really just combinations of all the bits and pieces that an application needs to run. The virtual IP is very important, as it is the central load balancer that allows the application to be accessible no matter which node it's running on. I'm going to do that one more time because that was not a great take.
The virtual IP is a simple load balancer that allows the application to be available no matter what node it is running on. And finally, HA clustering focuses more on quick failover for more common, but less impactful, issues while DR focuses on issues that could bring down an entire data center.
Thank you so much for listening to this video. I hope you got a lot from it, and I hope you have a great symposium.

In this video, we discuss the topic of availability in distributed systems.
We categorize organizations based on their acceptable levels of availability, ranging from startups to mature companies aiming for five to six nines of availability.
InterviewReady: https://interviewready.io/
We share a real-world example of a startup facing availability challenges with its database hosted in the wrong region. The solution involves migrating the database to a more suitable location and implementing a step-by-step process to minimize downtime.
Here are five principles for building highly available systems:
1. Simplicity over Perfection
2. Downtime Over Loss
3. Lesser Moving Parts
4. Chaos Engineering
5. Incident Reports and Root Cause Analysis
We also touch upon fault tolerance strategies such as redundancy, load balancing, and database replication to ensure high availability in distributed system components.
Engineers should either leverage existing highly available systems or adopt a principled approach to building and maintaining availability in their systems.

Failover is the technique of switching to a redundant backup machine when a certain node goes down. This is a very common implementation for achieving high availability and it is often mixed with different load balancing techniques such as layer 4 and layer 7 balancing.

Welcome to ScienceLogic Symposium 2021. My name is Jesse Triplett. I'm a Senior Support Engineer with ScienceLogic Support, and in this video, we're going to cover the basics between HA and DR cluster. So let's get started.
This video will be covering the basics of a heartbeat network, services and the resources that make them up, virtual IPs or VIPs and what the differences are between HA and DR clusters.
In short, the heartbeat network is merely a network through which the primary and secondary nodes pass back and forth a token. Each node expects that token to come back around in a configured amount of time. If that token does not come back around, then the cluster will begin a a failover process. This is the top level cluster health check for your cluster.
Services are made up of resources. These resources can be anything that an application needs to run. That includes mounted storage, file systems, the software for the application itself, really anything. For SL1, we specifically use distributed replicated block devices, a backend database made of MariaDB, the processes and parts of the application for SL1 itself, as well as a virtual IP. The VIP is a secondary IP that is applied to the public-facing primary NIC on the node that is currently running the SL1 stack. What this means is that any system that accesses that VIP is sure to get the SL1 stack itself and not the non-active node. It is, in that way, a very simple load balancer.
When it comes to HA versus DR, the easiest way to describe it is that HA is meant for and focuses on immediate and automated failover from one node to another. This means, if for some reason, one node cannot run the surface, the other note will pick up the slack. What makes DR, or disaster recovery clusters, different is that instead of focusing on server-level issues that would prevent a server from being able to run the application, such as a hypervisor failure, disaster recovery focuses more on less common, but more impactful, issues that may bring down an entire data center. For that reason, you have a primary node and a secondary node that is offsite in a separate data center.
Because of the distance between these two nodes and the latency between them, this means that in the case of a failure situation, some user intervention will be required. That is the difference you are most likely to notice between running an HA cluster and the DR cluster. It's also important to note that you can run an HA cluster with a DR node for maximum stability and uptime.
I hope this video made clear that the heartbeat is the primary cluster level health check of the nodes themselves, that highly available services are really just combinations of all the bits and pieces that an application needs to run. The virtual IP is very important, as it is the central load balancer that allows the application to be accessible no matter which node it's running on. I'm going to do that one more time because that was not a great take.
The virtual IP is a simple load balancer that allows the application to be available no matter what node it is running on. And finally, HA clustering focuses more on quick failover for more common, but less impactful, issues while DR focuses on issues that could bring down an entire data center.
Thank you so much for listening to this video. I hope you got a lot from it, and I hope you have a great symposium.

In this video, we discuss the topic of availability in distributed systems.
We categorize organizations based on their acceptable levels of availability, ranging from startups to mature companies aiming for five to six nines of availability.
InterviewReady: https://interviewready.io/
We share a real-world example of a startup facing availability challenges with its database hosted in the wrong region. The solution involves migrating the database to a more suitable location and implementing a step-by-step process to minimize downtime.
Here are five principles for building highly available systems:
1. Simplicity over Perfection
2. Downtime Over Loss
3. Lesser Moving Parts
4. Chaos Engineering
5. Incident Reports and Root Cause Analysis
We also touch upon fault tolerance strategies such as redundancy, load balancing, and database replication to ensure high availability in distributed system components.
Engineers should either leverage existing highly available systems or adopt a principled approach to building and maintaining availability in their systems.

High availability
High availability is a characteristic of a system, which aims to ensure an agreed level of operational performance for a higher than normal period.
There are three principles of system design in high availability engineering:
Modernization has resulted in an increased reliance on these systems. For example, hospitals and data centers require high availability of their systems to perform routine daily activities. Availability refers to the ability of the user community to obtain a service or good, access the system, whether to submit new work, update or alter existing work, or collect the results of previous work. If a user cannot access the system, it is - from the users point of view - unavailable. Generally, the term downtime is used to refer to periods when a system is unavailable.

Bus Stops
by: Nonce[Chorus:]
They on the bus stops
They out bumpin' the sound
They at every mall in the city
Take a look at `em cruising around
[x2]
[Nouka:]
I seen this girl yo around the way
She kicked over there where my homegirl stay
I've been known to step up and make them swoon to me
It's just a job of being devastating MCs
When I'm looking for a freak you know it ain't no stress
I get they minds tight and then you out that dress
So when I roll up and say what's your name
Showing them thighs driving me insane
Don't try to front cause I saw you look
I know your thinking `bout how much time I took
So now I'm out on the town with my alias
Getting all freaks in my radius
Shine was fly so was Michelle
Denise and Keanna broke me off real well
So if you in the city and you got it like that
Yusef won't you tell `em where the honeys is at
[Chorus]
[AceyAlone:]
Hey, goes down_I'm AceyAlone on WKAC on your FM dial
Now this is to all the ladies, a little something for your tummies
Now where they at_
[Yusef:]
Now I am not the one to be flossing see
About the Janes everyday that'll flock to me
And yes I see them round the way cause they all got fame
You know the brothers realize cause we peep that game
From LaShawn down to Kim plus Antoinette
Little Keesha and Shareeka can't forget Fissette
For the jibs that'll make a nigger nature rise
You see I gotta put them down just to recognize
From the neighborhood spot where they all might gather
From the phone conversation to the latest fad
I can't front or even stop cause the spot's quite hot
And like without the proper biz then you must shake the spots
So if you get an eye then you best pursue
Cause if your line's kind of late another John will do
And if, you see Tamika tell her give me a ring
Now I'm a let the cable go so the guys can sing
[Chorus]
[Nouka:]
In summer dresses and braided hair
And faded fros really make me stare
I'm talking `bout the girls who really know
Who nod they heads when the beat is slow
Sherrelle is the girl with the attitude
But I handled that right when I'm in the mood
Shae is the girl who's paging me
I'll call her when I'm finished on this M-I-C
One day I asked Kiki what her homegirls say
They say who is that baller over there today
Seeing these Janes is routine you see
I even like the girls who jock constantly
It's not that I be flossing nor nothing like that
I guess I'm just a player with that old school rap
Now if the sun is shining and it's really hot
My man won't you tell them `bout them honey spots
