In cloud computing, serverless architecture has revolutionized how applications are conceived, built, and managed. Often dubbed as Function as a Service (FaaS), serverless computing is a cloud model where infrastructure management is delegated to the provider. Resources are allocated dynamically to execute code in the form of functions. This abstraction liberates developers from server concerns, enabling them to focus solely on crafting code and defining function behavior.

The roots of serverless computing can be traced back to the emergence of Platform as a Service (PaaS), gaining significant traction with the introduction of AWS Lambda in 2014. Today, leading cloud providers like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) offer their serverless solutions, ushering in a new era of cloud computing.

How Serverless Works

Serverless applications operate on an event-driven architecture, where functions respond to specific triggers such as HTTP requests, database changes, or queue messages. This approach ensures that serverless functions execute only when necessary, eliminating the need for idle infrastructure. At the heart of serverless computing lies the Function as a Service (FaaS) model. In FaaS, developers create stateless functions tailored for specific tasks. These functions are deployed to a serverless platform and wait for triggers or events to initiate execution. The serverless platform handles resource allocation, execution, and automatic scaling in response to fluctuating workloads.

Statelessness is a key feature of serverless functions. The functions do not retain any persistent state between invocations, guaranteeing easy scalability as each execution is self-contained and doesn't rely on prior states. The serverless platform efficiently manages scalability by provisioning resources as needed to accommodate variable workloads.

Benefits of Serverless Computing

• Cost Efficiency: Serverless computing offers cost benefits by eliminating the need to provision and maintain idle infrastructure. Organizations only pay for the actual computing time used by functions, reducing operational costs.
• Scalability and Auto-scaling: Serverless platforms automatically scale functions in response to increased workloads. This auto-scaling capability ensures that applications remain responsive even during traffic spikes.
• Simplified Management: Serverless architectures simplify infrastructure management, as cloud providers handle tasks such as server provisioning, patching, and scaling. This allows development teams to focus on code and application logic.
• Reduced Development Time: Serverless development can accelerate the development cycle, as developers can quickly iterate on functions without managing infrastructure. This agility translates into faster time-to-market for applications.

Challenges and Considerations

• Cold Starts: In serverless computing, "cold starts" present a challenge. This term refers to a slight delay when starting a function for the first time. These initial delays can impact response times, especially for functions that are rarely used.
• Vendor Lock-In: Adopting serverless platforms may lead to vendor lock-in, as each provider offers proprietary services and event triggers. Migrating serverless applications between providers can be a complex and challenging process.
• Monitoring and Debugging: Monitoring and debugging serverless functions can prove more intricate than traditional architectures. Serverless functions are short-lived and may execute concurrently. To effectively manage these functions, utilizing appropriate tools and best practices is crucial.
• Security Concerns: Security is a paramount consideration in serverless applications. This includes ensuring the security of functions, handling sensitive data appropriately, and implementing robust access controls. Misconfigurations within functions can introduce security vulnerabilities.

Serverless vs. Traditional Cloud Computing

Comparing serverless with traditional virtual machine (VM)-based architectures highlights the differences in resource management, scalability, and cost. Serverless excels in certain scenarios, while VMs remain relevant for others. Serverless is well-suited for specific tasks such as handling asynchronous events, real-time processing, and lightweight APIs.

Real-World Applications of Serverless Computing

• Web and Mobile Backends: Serverless is well-suited for web and mobile backends. Functions can handle tasks like HTTP requests, authentication, and data processing. It offers scalability to match user demand.
• IoT (Internet of Things) and Edge Computing: In IoT applications, serverless functions at the edge can process data from sensors and devices in real-time, enabling rapid decision-making and reducing latency.
• Data Processing and Analytics: Serverless platforms excel in data-related tasks such as data transformation, ETL (Extract, Transform, Load), and real-time analytics. They process data from various sources and provide valuable insights.
• AI and Machine Learning: Serverless architectures simplify the deployment of machine learning models, making it easier to integrate AI capabilities into applications.

 Best Practices for Serverless Development

• Designing Stateless Functions: Embrace the stateless nature of serverless functions to ensure that they can scale effectively and remain independent of previous invocations.
• Effective Logging and Monitoring: Implement comprehensive logging and monitoring practices to track function performance, troubleshoot issues, and gain insights into application behavior.
• Version Control and CI/CD: Apply version control to serverless functions, automate deployments with continuous integration and continuous delivery (CI/CD) pipelines, and use infrastructure as code for reproducibility.
• Handling Dependencies: Be mindful of function dependencies, manage external libraries carefully, and consider strategies like packaging dependencies with functions to avoid performance bottlenecks.

A hybrid cloud model combines a private cloud with one or more public cloud solutions. In a hybrid cloud model, proprietary software enables communication between distinct services. This type of cloud computing model can help gain security advantage provided some critical challenges are addressed.

Following are crucial cybersecurity risks that need to be identified and addressed before implementing the hybrid cloud model:

• Compliance: A hybrid cloud model involves data movement between high-security private cloud and comparatively less secure public cloud. Such data movement may induce compliance issues and make data vulnerable to breaches. Businesses need to take extra measures to ensure that the hybrid cloud model meets compliance requirements. It may be achieved by ensuring that individual private and public cloud networks meet standard data security norms such as GDPR (General Data Protection Regulation). Also, it is important to make sure that the data transfer mechanisms adhere to regulatory requirements.

• Data Privacy: The essence of hybrid cloud model lies in flexible data movement between public cloud and private cloud. In such movement, there are high chances that the data can fall prey to intruder attacks that challenge the organization’s data privacy rules. Organizations should employ measures such as endpoint verification protocol, robust VPN, and strong encryption policy. These measures help in encrypting and protecting data from security breach incidents.
  
• Distributed Denial of Service: DDoS is another serious cyber-attack that can be initiated from multiple sources to target a single location. Since the attack has various source locations, it becomes difficult to trace and detect. This increases the risk factor. To tackle this, organizations need to maintain a strict monitoring system that can track the inflow and outflow of data. It is important to make sure that the monitoring system should be scalable, responsive, and able to handle multi-vector attacks.
  
• Service Level Agreements (SLA): Employing a hybrid cloud solution means handing over data governance and accountability to its public Cloud Service Provider (CSP). If the security of such a public cloud is compromised, it can be a severe issue and may lead to critical data loss. To avoid such issues, be careful while signing Service Level Agreements with the service provider to ensure data confidentiality. Make it a point to understand security limitations and strictly define accountability factors.
  
• Risk Management: Organizations should employ adequate risk management and preventive safety measures to protect their intellectual property from potential risks. Organizations can use tools such as IDS/IPS to scan malicious traffic. Also, maintain a log monitoring system with advanced firewall and security management features.
  
• Data Redundancy: Organizations should adopt a well-defined data redundancy policy to ensure timely backup of critical data. This can be achieved by maintaining multiple data centers. It also helps in continuing business services during data center outages.

Although the term ‘Serverless Computing’ implicates the existence of a computing architect with no server, it actually defines a cloud based execution model. The server is hosted by cloud service providers and users are not required to buy it or set it up onsite. The cloud service provider manages the server and machine resources are allocated to users.

As most businesses are making a shift towards serverless computing instead of traditional approach, it is necessary to understand the pros & cons of this approach.

Pros Of Serverless Computing:

1. Cost-effective: Serverless computing is a cost-effective approach for businesses. The users are required to pay as per the amount of resources consumed by their application instead of pre-purchased units of usage capacity.

2. Easy To Scale Up: In case of serverless computing, application developers are not required to implement a code for scaling up. Also, it rules out the need and cost for upgrading existing servers or adding new server units. When considering to scale up, businesses can request additional resources from the service provider and pay according to their consumption. Also, cloud systems are more elastic as they are capable of scaling up and down inherently according to the demand.

3. Low Human Resources Cost: Serverless computing eliminates the need for onsite servers. Thus, businesses are not required to hire staff for managing and operating the hardware. This helps them save cost that was traditionally incurred on human resources.
