The best Oracle blogs from thousands of blogs on the web ranked by traffic, social media followers, domain authority & freshness.
Happy to share that my blog has been choosen for another year as the Top 100 Blogs around the world, the list contains talened, experience and professional people 🎉🎉🎉
Thank you all for the support.

All-at-once
All-at-once deployments instantly shift traffic from the original (old) Lambda function to the updated (new) Lambda function, all at one time. All-at-once deployments can be beneficial when the speed of your deployments matters. In this strategy, the new version of your code is released quickly, and all your users get to access it immediately.
Canary
A linear deployment is similar to canary deployment. In this strategy, you direct a small amount of traffic to
In a canary deployment, you deploy your new version of your application code and shift a small percentage of production traffic to point to that new version. After you have validated that this version is safe and not causing errors, you direct all traffic to the new version of your code.
Linear
A linear deployment is similar to canary deployment. In this strategy, you direct a small amount of traffic to your new version of code at first. After a specified period of time, you automatically increment the amount of traffic that you send to the new version until you’re sending 100% of production traffic.
Comparing deployment strategies
To help you decide which deployment strategy to use for your application, you’ll need to consider each option’s consumer impact, rollback, event model factors, and deployment speed. The comparison table below illustrates these points.
| Deployment | Consumer Impact | Rollback | Event Model Factors | Deployment Speed |
|---|---|---|---|---|
| All-at-once | All at once | Redeploy older version | Any event model at low concurrency rate | Immediate |
| Canary/ Linear | 1-10% typical initial traffic shift, then phased | Revert 100% of traffic to previous deployment | Better for high-concurrency workloads | Minutes to hours |
Traffic shifting with aliases is directly integrated into AWS SAM. If you’d like to use all-at-once, canary, or linear deployments with your Lambda functions, you can embed that directly into your AWS SAM templates. You can do this in the deployment preferences section of the template. AWS CodeDeploy uses the deployment preferences section to manage the function rollout as part of the AWS CloudFormation stack update. SAM has several pre-built deployment preferences you can use to deploy your code. See the table below for examples.
| Deployment Preferences Type | Description |
|---|---|
| Canary10Percent30Minutes | Shifts 10 percent of traffic in the first increment. The remaining 90 percent is deployed 30 minutes later. |
| Canary10Percent5Minutes | Shifts 10 percent of traffic in the first increment. The remaining 90 percent is deployed 5 minutes later. |
| Canary10Percent10Minutes | Shifts 10 percent of traffic in the first increment. The remaining 90 percent is deployed 10 minutes later. |
| Canary10Percent15Minutes | Shifts 10 percent of traffic in the first increment. The remaining 90 percent is deployed 15 minutes later. |
| Linear10PercentEvery10Minutes | Shifts 10 percent of traffic every 10 minutes until all traffic is shifted. |
| Linear10PercentEvery1Minute | Shifts 10 percent of traffic every minute until all traffic is shifted. |
| Linear10PercentEvery2Minutes | Shifts 10 percent of traffic every 2 minutes until all traffic is shifted. |
| Linear10PercentEvery3Minutes | Shifts 10 percent of traffic every 3 minutes until all traffic is shifted. |
| AllAtOnce | Shifts all traffic to the updated Lambda functions at once. |
When you check a piece of code into source control, you don’t want to wait for a human to manually approve it or have each piece of code run through different quality checks. Using a CI/CD pipeline can help automate the steps required to release your software deployment and standardize on a core set of quality checks.

The Idea of this project the following :
You need to develop and deploy a python app that writes a new file to S3 on every execution. These files need to be maintained only for 24h.
The content of the file is not important, but add the date and time as prefix for you files name.
The name of the buckets should be the following ones for QA and Staging respectively:
qa-FIRSTNAME-LASTNAME-platform-challenge
staging-FIRSTNAME-LASTNAME-platform-challenge
The app will be running as a docker container in a Kubernetes cluster every 5 minutes. There is a Namespace for QA and a different Namespace for Staging in the cluster. You don’t need to provide tests but you need to be sure the app will work.

Thank you
so this what i did to make the import faster ( which i completed it as well ) :-
You need to download the following files & upload them to the server :-
#ls -lrt

#pkg publisher
PUBLISHER TYPE STATUS URI
solaris origin online http://pkg.oracle.com/solaris/release/
as you see from the above output package publisher still working under oracle Link. Let’s Start Working, Set the executable bit for install-repo.ksh and execute like below.
#./install-repo.ksh -d /export/oracle/repo/ -v -c
Comparing checksums of downloaded files…done. Checksums match.
Uncompressing sol-11_2-repo-1of4.zip…done.
Uncompressing sol-11_2-repo-2of4.zip…done.
Uncompressing sol-11_2-repo-3of4.zip…done.
Uncompressing sol-11_2-repo-4of4.zip…done.
Repository can be found in /export/oracle/repo/.
Initiating repository verification.
Again Check the current publisher.
#pkg publisher
PUBLISHER TYPE STATUS P LOCATION
solaris origin online F http://pkg.oracle.com/solaris/release/
configure the new publisher, Path should be the same.
#pkg set-publisher -G ‘*’ -M ‘*’ -g file:///export/oracle/repo solaris
#pkg publisher
UBLISHER TYPE STATUS P LOCATION
solaris origin online F file:///export/oracle/repo
Configure the repository service to point to the new location by run the following command :-
# svccfg -s application/pkg/server setprop pkg/inst_root=/export/oracle/repo
Check
# svcprop -p pkg/inst_root application/pkg/server
Reload the Services Just to confirm :-
# svcadm refresh application/pkg/server
