OMP & TLOC Attributes Let us discuss more about OMP and tlock routes. So what is happening? Say in case of OMP, if the device that you will get that is a new device in your site, inside that you will find that OMP configuration will be by default. So OMP and some of the advertised commands will be there. OMP advertise, connected, OMP advertisement is static, those things will be there. You can see connected and static by default will be there. Obviously you can go and change and…

OMP TLOC Begins Here .. Now from section three dot two up to three dot four, you can see that we have to measuredly, focus on underlay and overlay plus the redundancy in terms of tlock extension. So in this section first of all three dot two will start with the verification of the data plane tunnels and other verification then the tlock extension. Now tlock is important key factor we have it is the communication channel beneath and above. That means the underlay and overlay. With help of tlock…

What are Device Configuration Template Let us discuss more about the template. So, what are the configurational template? More precisely the device configuration template devices say define all device configuration parameter, enforce device configuration consistency compliance across entire networks. So what these things is that okay, if you are managing everything from the we manage, then you can and maintain the standardization and you can maintain the common type of template. And that’s the term called a standardization to all the branches. Either it’s type one, type two, type three…

Aurora failover priorities in action – Demo In this demo. Let’s look at how failure tiers work when we have replicas of different sizes. Here I have an Aurora MySQL cluster with one Writer and four read replicas. And you can see that these replicas are placed in different az’s and they are also of different sizes. We have one reader which is of size two X large. We have another reader which is of size X large. The third reader is also of the size X large. And then…

Cloning databases in Aurora Now let’s look at Cloning databases in Aurora. So Cloning is different from creating read replicas clone support reads as well as rights and Cloning is also different from replicating a cluster because clones use the same storage layer as the source cluster and you’ll understand what I mean in just a bit. So the clone database is run using the same storage layer as the original database, so it only requires a minimal additional storage. So this is very cost effective option of creating read…

Scaling options in Aurora Now let’s look at scaling in Aura. So you have three types of scaling. In Aura, we can have storage scaling, we can have compute scaling, and we also have auto scaling options. Let’s look at storage scaling first. This is built in and automatic. And we already know that storage scales from ten gigs to about 64 TB and it scales in tang increments, okay? And of course the 64 TB is a soft limit. You can request AWS support to increase this limit if…

Data API for Aurora Serverless Aura serverless also provides what is called as Data API. So when you talk to Aura Serverless, you can run queries over APIs. Instead of using a DB connection and firing your SQL queries using a SQL client, you simply run your queries over the API. And you can also run queries using the query editor that’s available within the RDS console. It looks something like this, and you can simply type in your queries and you will get the response right within your RDS…

DynamoDb backup and restore – Hands on Now, let’s quickly look at the backup and restore features in DynamoDB. So here is our gameplay table, and I’m going to go on the Backups tab. This is where you can create backups and restore from existing backups. Before we create a backup, let’s look at the items in the table. So we have these two items here, right? And what we’re going to do is create a backup to go on the Backup tab and create a backup. Let’s name it…

DynamoDB accelerator (DAX) In this lecture, we are going to look at DAX, or DynamoDB Accelerator. So DynamoDB accelerator, or DAX is inmemory caching service that sits on top of Dynamo TB. And we already know that Dynamo TB provides us with single digit millisecond latency. And if that’s not enough, and if your application requires even more faster performance, you can use Tax on top of your DynamoDB tables. And that’s going to give you ultra low latencies. Like in Microseconds, a Tax cluster sits in between your DynamoDB…

DynamoDB partitions In this lecture, we’re going to talk about the DynamoDB partitions. This is going to help you understand how DynamoDB works under the hood. So what exactly is a DynamoDB partition? Now, the partitions store the Dynamo TB table data physically, all right? The partitions are actually ten gig SSD volume volumes, which physically store your table data. Now, you should not confuse this with your tables partition key or the hash key, because the partition K is a logical partition, whereas the DynamoDB partition is a physical…
