Oracle Cloud Certification News

 
Today we are going to talk a little about certification and some changes, I think it’s a cool theme for those looking to study to get a certification in Oracle Cloud.
We can see that several exams from Oracle’s Cloud universe are constantly updated, I’m using as an example the part of Oracle Cloud Infratructure Services, where 2 new certification levels were released.
Can we see that the 1Z0-932 and 1Z0-1072 test are the same concepts but what are the main differences?
There is not much difference in the content of both the certifications (Modules are the same).
 
The 1Z0-932 is the 2018 version of the Architect Associate certification.
 
The 1Z0-1072 certification is the 2019 version of the Architect Associate Exam. You’ll get the questions for all the changes which have been done in 2018 to till now.
In September 2019, 1Z0-997 was launched, where the practical experience and knowledge needed to plan, design, implement and operate solutions in OCI is charged. The skills validated by this certification include:
 
  • Plan and design solutions; implement and operate solutions;
  • Design, implement and operate databases;
  • Design for hybrid cloud architecture;
  • Migrate on-premises workloads to OCI;
  • Design for Security and Compliance
 
Finally to 1Z0-1067, comes to charge the knowledge required to Automate Cloud tasks, Tune Performance, Troubleshoot, manage cost, manage security and compliance policies, Monitor and Alert OCI, Implement Data Retention and Archival, creating shell scripts with the Command Line Interface (CLI) and design Cloud-scale Agility on OCI.
Oracle Cloud Infrastructure Services
 
  • 1Z0-932 – Oracle Cloud Infrastructure 2018 Architect Associate
  • 1Z0-1072 – Oracle Cloud Infrastructure 2019 Architect Associate
  • 1Z0-997 – Oracle Cloud Infrastructure 2019 Architect Professional
  • 1Z0-1067 – Oracle Cloud Infrastructure 2019 Cloud Operations Associate
If you haven’t done any OCI certification yet & are planning to take the exam, is need attention in the new Recertification policy.
Cloud Certifications
Oracle Cloud Certification credentials are valid for a period of 18 months from the date you earn the credential. The credential will become inactive at the end of 18 months. Oracle requires candidates to hold an active credential in order to access certain certification benefits including, without limitation, use of Oracle certification logos, eCertificates, score reports, digital badges and certification verification. To stay current, candidates must re-certify themselves with the latest version of the exam. Oracle Cloud Certifications include Oracle Certified Associate, Specialist and Professional titles. Oracle Cloud Certifications are updated continuously throughout the year to keep current with major product and service releases, and re-released on an annual basis with a new title.
Note:
(1) Credentials earned by passing 2019/future exams after 12-Sep-2019 will remain active for 18 months from the date of earning them
(2) Credentials earned by passing 2019 exams on or before 12-Sep-2019 will remain active till 12-Mar-2021
(3) Credentials earned by passing 2018/older exams will remain active till 01-Jun-2020
 
I hope this helps you!!!

New Features – OCI
Category: Cloud Author: Andre Luiz Dutra Ontalba (Board Member) Date: 5 years ago Comments: 0

New Features - OCI

 
 
Today I decided to write a post with the new features that have been released in OCI in recent months.
 
I will be making detailed articles on each of these features as soon as possible.
 
Let’s go now with the new features
 
𝐎𝐒 𝐌𝐚𝐧𝐚𝐠𝐞𝐦𝐞𝐧𝐭 𝐒𝐞𝐫𝐯𝐢𝐜𝐞
 
– Service Available from OCI Console
– Managed instance can be managed individually or in group.
 – Easy Instance grouping – By OS or By Purpose of Instances – Easy Bulk Operations
 – Select or Create Custom software sources.
– Immediate execution as Work Request or Scheduled Jobs for OS Package Management.
– Checking for Exposures to known Common Vulnerabilities and Exposures (CVE).
– Agent based Service for Linux 6,7 or 8 Instances.
– OS Management enabled by default only Agent install needed via yum.
– For Service Operation Agent (osms-agent) must be installed.
– Compute + OS Management = Managed Instance
– Enables Package Management – Monitor, Search, Add, Remove, Update
𝐁𝐥𝐨𝐜𝐤 𝐕𝐨𝐥𝐮𝐦𝐞 𝐒𝐡𝐚𝐫𝐢𝐧𝐠 𝐑𝐞𝐚𝐝-𝐖𝐫𝐢𝐭𝐞 𝐌𝐨𝐝𝐞

 

– Two options introduced Read/Write Sharable and Read-only Sharable.
– Read-Write needs Clusterware solution on top of shared block volume.
– Read-only attachment are available in sharable mode to multiple instances.
– No need of concurrency access control or cluster-ware solution for Read-only Attach.
– Volume groups, Disk-to-Disk Clone, automated backups are available for Shared Block Volumes.
– Default attachment from Compute is non-shareable and exclusive read/write
– Available in all regions via OCI Console, CLI, SDK, Terraform.
 – Other vendors provide only Read-only Block Volumes but has limitation on Read-Write shareable attach.
Get back the Deleted Compartment.

 

– Once compartment is deleted it will be appended with random string.
– Use Filter Deleted Compartment to get the list.
– Audit Retention period is 90-365 days.
– Restore Compartment Option will allow you to restore compartment with the same appended string name.
– It will be listed in compartment list.
– All policies refer to the deleted compartment will be now pointed to restored compartment name.

 

 

I hope this helps you!!!

Block Volume Elastic Performance – OCI
Category: Cloud Author: Andre Luiz Dutra Ontalba (Board Member) Date: 5 years ago Comments: 0

Block Volume Elastic Performance - OCI

Oracle introduced a new feature to control the performance of Block Volume that is the Volume Performance Unit (VPU). It’s easy to manage and can be controlled with Console, API, and CLI. Its dynamic nature makes it the best option.

 

 

What Is Block Volume?
It provides high-performance constant Cloud storage in a wide range of application workloads. The Block Volume helps to provide network storage that can be used with OCI instances.
 
 
Volume Performance Unit (VPU) – New Feature
  1. Oracle charges it according to the performance units per GB per month.
  2. Higher IOPS and throughput corresponds to higher VPU.
  3. VPU is inversely proportional to the cost of the storage.
  4. Measured in terms of IO per sec and Throughput per GB.
 
 
For Block Volume Elastic Performance, there are three elastic performance configuration options, as described below.
 
 
Balanced: This is the default setting for new and existing block and boot volumes. It provides a good balance between performance and cost savings for most workloads, including those that perform random I/O such as boot volumes. This option provides linear peformance scaling with 60 IOPS/GB up to 25,000 IOPS per volume. Throughtput scales at 480 KBPS/GB up to a maximum of 480 MBPS per volume. With this option you are purchasing 10 VPUs per GB/month.
 
 
Higher Performance: Recommended for workloads with the highest I/O requirements, requiring the best possible performance, such as large databases. This option provides the best linear performance scale with 75 IOPS/GB up to a maximum of 35,000 IOPS per volume. Throughput also scales at the highest rate at 600 KBPS/GB up to a maximum of 480 MBPS per volume. With this option you are purchasing 20 VPUs per GB/month.
 
 
Lower Cost: Recommended for throughput intensive workloads with large sequential I/O, such as streaming, log processing, and data warehouses. The cost is only the storage cost, there is no additional VPU cost. This option gives you linear scaling 2 IOPS/GB upt to a maximum of 3000 IOPS per volume. This option is only available for block volumes, it is not available for boot volumes.
 
 
The following table lists the performance characteristics for each elastic performance level.

Configuring Volume Performance

 

 

You can configure the volume performance for a block volume when you create a volume. You can also change the volume performance for an existing block volume.

 

 

Create a new volume

 

 
Log into Oracle Cloud and click the Block Storage and select Block Volumes.
Click in Create Block Volume
Enter the details of Block Volume and click the “Create Block Volume”

 

Name: BV_PERF_UNIT

Compartment : <keep value>

Availability Domain : <keep value> 

Size (in GB) : 50

Compartment for Backup Policies : <keep value>

Backup Policy:  Bronze

Volume Perfomance : Lower Cost – For this example

Encryption : Encrypt
This process will take between 1 and 2 minutes to complete.
Change the volume performance

 

Log into Oracle Cloud and click the Block Storage and select Block Volumes.
Select your block volume. For this example BV_PERF_UNIT
Click in the “Change Performance”
Now it’s possible you select the best options for your environment.  For this test let’s select the “Balanced” and click in “Change Performance”
This process will take between 1 and 2 minutes to complete.
On the Storage pricing, Oracle has added Block Volume Performance unit which is priced as
Performance Units Per GB/Month
  • 0 VPUs at $0 for Lower Cost
  • 10 VPUs at $0.017 for Balanced
  • 20 VPUs at $0.034 for Higher Performance

 

As of now, OCI Block Volume Elastic Performance has 2 limitations:

 

  • Only changes Block volumes elastic performance configuration on three volumes concurrently per tenancy.
  • Boot volumes only have 2 options: Balanced or Higher performance.

 

This feature is definitely going to help the customer on the performance side and will save the costs as well.

 

I hope this helps you!!!
