<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p><strong>In-Place Deployment</strong></p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>The new version of the application replaced the previous version through deployment to the existing instances. You can use this strategy for applications that can only tolerate a shorter downtime during the deployment phase.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p><strong>Blue/Green Deployment</strong></p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Instead of deploying the new version of the application to the existing instances (Blue), it is deployed on separate instances (Green). After validating the new version, all the traffic gets shifted from Blue to Green instances.&nbsp;&nbsp;</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p><strong>Canary Deployment</strong></p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>CodeDeploy shifts the traffic present on the existing instances to the new version gradually and that too in small increments. Due to this, the errors and issues are detected early during the deployment process.</p>
<!-- /wp:paragraph -->

<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>The best serverless compute service offered by AWS is AWS Lambda. Using this service will eliminate the need of managing the servers. If you make use of AWS Lambda then your job would be to upload the code only while AWS takes care of the infrastructure. Along with this, AWS also takes care of the scalability. Using serverless computing will provide you with the following benefits.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p><strong>Scalability</strong></p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Lambda performs automatic scaling of your application in response to the traffic. When a function is executed, it is counted as a single and independent event. This enables on-demand scaling.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p><strong>Cost-Efficiency</strong></p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>You will not be charged for hidden services. Only the compute time which is consumed by your code will generate its bill. You don’t even have to pay for idle server time.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p><strong>Event-Driven Model</strong></p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Lambda functions hold this specialty that they can be triggered by external events and AWS services. It allows you to build event-driven architectures.</p>

<!-- wp:list -->
<ul><!-- wp:list-item -->
<li><strong>Performance Bottlenecks</strong></li>
<!-- /wp:list-item --></ul>
<!-- /wp:list -->

<!-- wp:paragraph -->
<p>When there is resource limitation or presence of inefficient code then the issue of bottleneck arises.</p>
