The Road to Serverless – Introduction to Serverless on AWS

The Road to Serverless

During the early 2000s, I (Sheen) was involved in building distributed applications that mainly communicated via service buses and web services—a typical service-oriented architecture (SOA). It was during this time that I first came across the term “the cloud,” which was making a few headlines in the tech industry. A few years later, I received instructions from upper management to study this new technology and report on certain key features. The early cloud offering that I was asked to explore was none other than Amazon Web Services.

My quest to get closer to the cloud started there, but it took me another few years to fully appreciate and understand the ground-shifting effect it was having in the industry. Like the butterfly effect, it was fascinating to consider how past events had brought us to the present.

The butterfly effect is a term used to refer to the concept that a small change in the state of a complex system can have nonlinear impacts on the state of that system at a later point. The most common example cited is that of a butterfly flapping its wings somewhere in the world acting as a trigger to cause a typhoon elsewhere.

From Mainframe Computing to the Modern Cloud

During the mid-1900s, mainframe computers became popular due to their vast com‐ puting power. Though massive, clunky, highly expensive, and laborious to maintain, they were the only resources available to run complex business and scientific tasks. Only a lucky few organizations and educational institutions could afford them, and they ran jobs in batch mode to make the best use of the costly systems. The concept of time-sharing was introduced to schedule and share the compute resources to run programs for multiple teams (see Figure 1-1). This distribution of the costs and resources made computing more affordable to different groups, in a way similar to the on-demand resource usage and pay-per-use computing models of the modern cloud.

The emergence of networking – Introduction to Serverless on AWS

The emergence of networking

Early mainframes were independent and could not communicate with one another. The idea of an Intergalactic Computer Network or Galactic Network to interconnect remote computers and share data was introduced by computer scientist J.C.R. Lick‐ lider, fondly known as Lick, in the early 1960s. The Advanced Research Projects Agency (ARPA) of the United States Department of Defense pioneered the work, which was realized in the Advanced Research Projects Agency Network (ARPANET). This was one of the early network developments that used the TCP/IP protocol, one of the main building blocks of the internet. This progress in networking was a huge step forward.

The beginning of virtualization

The 1970s saw another core technology of the modern cloud taking shape. In 1972, the release of the Virtual Machine Operating System by IBM allowed it to host multiple operating environments within a single mainframe. Building on the early time-sharing and networking concepts, virtualization filled in the other main piece of the cloud puzzle. The speed of technology iterations of the 1990s brought those ideas to realization and took us closer to the modern cloud. Virtual private networks (VPNs) and virtual machines (VMs) soon became commodities.

The term cloud computing originated in the mid to late 1990s. Some attribute it to computer giant Compaq Corporation, which mentioned it in an internal report in 1996. Others credit Professor Ramnath Chellappa and his lecture at INFORMS 1997 on an “emerging paradigm for computing.” Regardless, with the speed at which technology was evolving, the computer industry was already on a trajectory for massive innovation and growth.

The first glimpse of Amazon Web Services

As virtualization technology matured, many organizations built capabilities to auto‐ matically or programmatically provision VMs for their employees and to run busi‐ ness applications for their customers. An ecommerce company that made good use of these capabilities to support its operations was Amazon.com.

During early 2000, engineers at Amazon were exploring how their infrastructure could efficiently scale up to meet the increasing customer demand. As part of that process, they decoupled common infrastructure from applications and abstracted it as a service so that multiple teams could use it. This was the start of the concept known today as infrastructure as a service (IaaS). In the summer of 2006, the com‐ pany launched Amazon Elastic Compute Cloud (EC2) to offer virtual machines as a service in the cloud for everyone. That marked the humble beginning of today’s mammoth Amazon Web Services, popularly known as AWS!

Cloud deployment models – Introduction to Serverless on AWS

Cloud deployment models

As cloud services gained momentum thanks to the efforts of companies like Amazon, Microsoft, Google, Alibaba, IBM, and others, they began to address the needs of different business segments. Different access models and usage patterns started to emerge (see Figure 1-2).

Figure 1-2. Figurative comparison of different cloud environments

These are the main variants today:

Public cloud

The cloud service that the majority of us access for work and personal use is the public cloud, where the services are accessed over the public internet. Though cloud providers use shared resources in their data centers, each user’s activities are isolated with strict security boundaries. This is commonly known as a multitenant environment.

Private cloud

In general, a private cloud is a corporate cloud where a single organization has access to the infrastructure and the services hosted there. It is a single-tenant environment. A variant of the private cloud is the government cloud (for example, AWS GovCloud), where the infrastructure and services are specifically for a par‐ ticular government and its organizations. This is a highly secure and controlled environment operated by the respective country’s citizens.

Hybrid cloud

A hybrid cloud uses both public and private cloud or on-premises infrastructure and services. Maintaining these environments requires clear boundaries on secu‐ rity and data sharing.

Enterprises that prefer running their workloads and consuming services from multiple public cloud providers operate in what is called a multicloud environment. We will discuss this further in the next chapter.

The Influence of Running Everything as a Service

The idea of offering something “as a service” is not new or specific to software. Public libraries are a great example of providing information and knowledge as a ser‐ vice: we borrow, read, and return books. Leasing physical computers for business is another example, which eliminates spending capital on purchasing and maintaining resources. Instead, we consume them as a service for an affordable price. This also allows us the flexibility to use the service only when needed—virtualization changes it from a physical commodity to a virtual one.

In technology, one opportunity leads to several opportunities, and one idea leads to many. From bare VMs, the possibilities spread to network infrastructure, databases, applications, artificial intelligence (AI), and even simple single-purpose functions. Within a short span, the idea of something as a service advanced to a point where we can now offer almost anything and everything as a service!
