<h2 class="wp-block-heading">Serverless computing will be an exciting adoption area, even outside of tech.</h2>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>Serverless computing is a relatively new approach to cloud computing that has gained a lot of traction in recent years. With serverless computing, developers can write and deploy applications without having to worry about managing the underlying infrastructure. This approach offers a range of benefits, including increased flexibility, scalability, and cost savings.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph {"align":"start","className":"has-text-align-start"} -->
<p class="has-text-align-start">While serverless computing has primarily been adopted by technology companies, there is significant potential for this technology to be used outside of tech as well. For example, serverless computing could be used in industries such as healthcare, finance, and manufacturing to improve operational efficiency and drive innovation.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph {"align":"start","className":"has-text-align-start"} -->
<p class="has-text-align-start">In healthcare, for instance, serverless computing could be used to develop and deploy applications that improve patient care and streamline administrative tasks. In finance, serverless computing could be used to develop and deploy applications that improve data security and streamline financial transactions. In manufacturing, serverless computing could be used to develop and deploy applications that optimize supply chain management and improve production efficiency.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph {"align":"start","className":"has-text-align-start"} -->
<p class="has-text-align-start">One of the key benefits of serverless computing is its ability to reduce costs by allowing businesses to pay only for the resources they use. This can be particularly beneficial for non-tech industries that may not have the resources to invest in expensive IT infrastructure.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph {"align":"start","className":"has-text-align-start"} -->
<p class="has-text-align-start">Another benefit of serverless computing is its ability to increase agility and innovation by allowing developers to focus on application development rather than infrastructure management. This can be particularly beneficial for non-tech industries that may not have a strong IT team in place.</p>

<h2 class="wp-block-heading">Cloud will power widespread AI adoption?</h2>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>Cloud computing has emerged as a key enabler of artificial intelligence (AI) adoption, providing businesses with the computing power and resources needed to develop, deploy, and scale AI applications. As a result, we are seeing widespread adoption of AI powered by cloud technologies.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph {"align":"start","className":"has-text-align-start"} -->
<p class="has-text-align-start">One of the main benefits of using cloud computing for AI is the ability to access and process large amounts of data. Cloud computing provides businesses with the ability to store and process vast amounts of data, which is critical for training and deploying AI models.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph {"align":"start","className":"has-text-align-start"} -->
<p class="has-text-align-start">Another benefit of using cloud computing for AI is the ability to access specialized hardware and software. Cloud providers offer a range of AI-specific services, such as machine learning platforms, natural language processing tools, and image recognition software. These tools enable businesses to build and deploy sophisticated AI applications without having to invest in specialized hardware and software.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph {"align":"start","className":"has-text-align-start"} -->
<p class="has-text-align-start">In addition to these benefits, cloud computing also provides businesses with the ability to scale AI applications rapidly. Cloud providers offer elastic computing resources, which can be scaled up or down as needed to meet changing demand. This is critical for businesses that need to deploy AI applications quickly and at scale.</p>
