Enterprise technology has changed substantially since the 1990s. Organizations that once concentrated much of their technology spending on telecommunications infrastructure and on-premises computing now manage cloud environments, cybersecurity programs, digital platforms, and enterprise applications that support nearly every business function.
Those changes can be traced through individual careers and across the industry. Toronto technology consultant Michael Rustom entered the business-to-business technology sector in 1995 and has worked through several of the major shifts that have reshaped enterprise IT over the past three decades.
Enterprise Technology Grew More Complex
When Rustom began his career with AT&T Canada, enterprise telecommunications formed a significant part of corporate technology planning. Building new customer relationships meant working with organizations investing in communications infrastructure that supported growing business operations.
The scope of enterprise technology expanded over the following decade.
By the time Rustom moved into account management roles at NexInnovations and later Sun Microsystems, technology projects frequently involved multiple business units. While managing Sun Microsystems’ relationship with BMO Financial Group, Rustom worked with business units including Capital Markets, Risk Management, Card Services, and Nesbitt Burns. Large organizations increasingly relied on technology across separate operating divisions, requiring greater coordination between business stakeholders and technical teams.
Infrastructure Became Part of a Larger Strategy
Later, Michael Rustom joined Toronto-based Scalar Decisions in 2005, when many organizations were investing heavily in data centre infrastructure while preparing for broader changes in enterprise computing.
His client portfolio included mining, financial services, media, and real estate industries with different operational requirements but a common dependence on enterprise technology. His responsibilities now covered data centre infrastructure, cloud computing, cybersecurity, managed services, professional services, and technology resale.
That wide range of duties mirrored ongoing changes within enterprise IT. Organizations were assembling technology programs that combined multiple disciplines rather than treating infrastructure, security, and consulting as separate initiatives.
One example occurred during Rustom’s work on the technology contract supporting the 2015 Pan Am Games. Delivering a project of that scale required coordination across technical specialists, client teams, and implementation resources.
Leadership Roles Expanded Alongside Industry Demands
As enterprise technology programs grew in scale, Rustom’s responsibilities expanded. He progressed from Account Executive to Director of Sales for Ontario and Quebec, then Vice President, Sales for Canada East, before assuming national responsibility for sales, marketing communications, partner alliances, inside sales, contract renewals, and sales operations.
His appointment as Vice President of Business Operations in 2018 came during another significant period of development in the technology sector, as commercial operations, engineering, consulting, marketing, and human resources increasingly operated together within connected business structures.
Independent Consulting Marks Another Shift
After years in executive leadership, Rustom established his independent consulting practice, Michael Rustom Inc., in Toronto in 2022.
His current work includes technology project consulting and business advisory engagements. One of his most notable assignments involved supporting the delivery of a national web portal with e-commerce capability, user registration and validation, training management, and reporting functions. The project expanded to approximately two and a half times its original scope as additional requirements were incorporated during delivery.
That type of engagement illustrates how enterprise technology projects continue to evolve. Modern initiatives frequently combine multiple business functions within a single implementation and often develop further as organizational requirements become more clearly defined.
The continued growth of independent consulting comes as more organizations seek experienced advisors who can provide strategic guidance and specialized expertise for complex technology initiatives.
Three Decades of Enterprise IT
The technologies used by large enterprises have changed considerably since Rustom’s career began in 1995. Telecommunications gave way to integrated enterprise infrastructure. Cloud computing became part of mainstream technology planning. Cybersecurity assumed greater importance across organizations. Technology projects increasingly involve multiple business disciplines.
From account manager to consultant, Michael Rustom has followed those developments from inside the industry. Viewed over nearly three decades, it provides a practical record of how enterprise technology has evolved and how the work surrounding enterprise IT has become increasingly interconnected.
