New Feature – Per-Second Billing for Compute and Autonomous Database.

New Feature - Per-Second Billing for Compute and Autonomous Database.

Oracle this month announced a new form of billing for Compute Instance and Autonomous Database with that the Oracle Cloud has a stronger platform for legacy applications moving to cloud and a new family of cloud native applications that rely on microservices and dynamic scaling.
 
Compute instances are now billed per second of usage, rather than per hour. This helps you reduce costs when using instances for short amounts of time. Virtual machine (VM) instances have a minimum charge of one minute. Bare metal instances have a minimum charge of one hour. After the first minute (for VMs) or the first hour (for bare metal instances), usage is billed in one-second increments.
 
With this billing model, usage of Compute and Autonomous Database is billed per-second. All prices continue to be quoted on an hourly basis.
Here are some details about this billing model:
 
  • All virtual machine (VM) Compute instances, including those with graphical processing unit (GPU) chips, are now billed per-second with a one-minute minimum.
 
  • All bare metal Compute instances, including those with GPU chips, are now billed per-second with a one-hour minimum.
 
  • Autonomous Data Warehouse and Autonomous Transaction Processing usage is now billed per-second with a one-minute minimum.
 
  • Windows OS images are now billed per-second with a one-minute minimum.
 
  • Microsoft SQL Server images available in the Oracle Cloud Marketplace are now billed per-second with a 744-hour (one month) minimum.
 
 
The workloads that will see the biggest impact from this change are those that stop and start frequently, and those that run for short durations. Here are some examples of significant benefits:
 
 
I believe that with this, Oracle increasingly invests and provides more resources and different ways for its customers to be able to plan and prepare their environments for the cloud.

I hope this short article has helped.

Oracle Autonomous Database and DevOps: A simple usage approach – Part 2
Category: Cloud Author: BRUNO REIS Date: 6 years ago Comments: 0

Oracle Autonomous Database and DevOps:
A simple usage approach – Part 2

            This article is the second part of the series of articles about Oracle Autonomous Database and DevOps. For a better understanding, I recommend reading the article “Oracle Autonomous Database and DevOps: A Simple Usage Approach – Part 1” before proceeding with the steps in this article.
 
As in the previous article the Docker configuration was handled, we will begin to provision the Oracle Autonomous Database version 18c in the Oracle Cloud.
 
– Provisioning the Oracle Autonomous Database in the Cloud: Before provisioning the database it is necessary to create a Compartment. If you have not yet created click on “Identity” and later on “Compartments” under the “Governance and Administration” tab of the menu:

 

 

Then click “Create Compartment” if there is no existing compartment: The root compartment is the first compartment created. From this it is possible to create other compartments by using it as an option in the “Parent Compartment” tab.
Fill in the required fields as the Name of the compartment, any description in the Description field and click on the “Create Compartment” link.
In the above example the name “brunoreis” was chosen as the name of the compartment. In addition, because Oracle recommends creating databases in compartments other than root, a compartment called TECHDATABASKET was created, represented by the image below:

 

Now with the compartment created we will proceed with the creation of the Autonomous Transaction Processing (ATP) instance.
 
On the Oracle Cloud menu, click Autonomous Transaction Processing:

 

Click the Create Autonomous Database button:
In the Create Autonomous Database tab fill in all requested information such as database name, CPU core, storage etc. An important note in this topic is that you can choose the type of workload as AUTONOMOUS DATA WAREHOUSE or AUTONOMOUS TRANSACTION PROCESSING. However, in this article we are only using the AUTONOMOUS TRANSACTION PROCESSING option.
Make sure you have provided all the information correctly and click on “Create autonomous database”:
 
 
During the creation of the database, we will be shown the status “Provisioning”
Once the provisioning is finalized, the status is changed to “Available”:
            In the next article we will discuss the connection between Oracle SQL Developer using the database wallet file created in the Oracle Cloud and also the creation of a Linux machine where the application will be implemented.

Interconnect Oracle Cloud and Microsoft Azure
Category: Cloud Author: Andre Luiz Dutra Ontalba (Board Member) Date: 6 years ago Comments: 0

Interconnect Oracle Cloud and Microsoft Azure

Last week, it was announced that Oracle and Microsoft have created a cloud-to-cloud connection between Oracle Cloud Infrastructure and Microsoft Azure in certain regions.
 
This connection allows you to configure workloads between clouds without traffic between the clouds that pass through the Internet.
 
OCI and Azure Interconnect services:
 
Limited to Azure East US (eastus) region and the OCI Ashburn (us-ashburn-1) region as of now.
ExpressRoute peering location is in proximity to or in the same peering location as the OCI FastConnect.
Identity side its common and well known integration between IDCS and Microsoft Active Directory.
Provides low latency and high throughput cross-cloud connectivity
Network Peering possible between Azure and OCI.
Multi-tier application can be partitioned to run DB on OCI and Application on Azure
Cross-Connect can be established ExpressRoute circuit in Azure and Fastconnect on OCI.
Traffic between the 2 providers over a private network.
Network traffic can be controlled using Security List (OCI) and Network Security Groups (Azure)
 
 
 
Link about official documentation:
https://docs.cloud.oracle.com/iaas/Content/Network/Concepts/azure.htm
 
Hope this helps. See you !!!

Create Database System in Exadata, Bare Metal or VM
Category: Cloud Author: Andre Luiz Dutra Ontalba (Board Member) Date: 6 years ago Comments: 0

Create Database System in Exadata, Bare Metal or VM

This article provides a run through of creating a Database System using Exadata, Bare Metal or VM on the Oracle Cloud.
 
Log into Oracle Cloud and click on  the “Bare Metal, VM and Exadata”  in the Database
 
Select the compartment you want to build the service in, then click the “Lauch DB System” button.

 

Enter the details of the service you want to create. We selected the VIRTUAL MACHINE type, because Bare Metal and Exadata were not available for our region.

We selected only 1 node to perform this article as we selected the Enterprise Edition Extreme Perfomance option. We will prepare another article explaining all the details of the differences from Shapes and Softwares to DB System.

Remember to select the appropriate licensing model. 

 

 

 

Now we will generate the keys to use in our DB System.
We recommend you generate a key using the Putty Key Generator.
Click Generate and move the mouse until the key is created

 

After it was created save a copy as Public Key and another as Private Key.
Now let’s put the public key to have access after the machine is created via SSH.

 

Click in Choose Files
 
 Select the file saved as Public Key, in my case Public_Keys. Pub
 
 After that, if you have not created any VNC (Virtual Network Circuit), it will be created automatically.  In my case I have already created then already came selected.

 

Now put information about the database and after that click Lauch DB System
Screen while creating the resource.
After an hour the environment was created, and we are asked why so much delay.

This answer is simple, building a DB System involves several components such as NETWORK, STORAGE, COMPUTE and software installation.

 

Ready your DB System is OK.
 
Now we will access the VM through SSH.
 
Take the IP that looks like for you in this item and open in an SSH client, remembering that we should use the private key now to make the connection.

In my case I access using mobaxterm, in Remote host I put the IP, select the username and type “OPC” and select Use the Private Key that was generated.

 

 

 

Ready server connected and ready to use your DB System.
Hope this helps. See you !!!
