Platform as a service (PaaS) is a cloud computing model that provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the underlying infrastructure.
PaaS offers a complete development and deployment environment in the cloud, including tools, libraries, middleware, databases, and runtime environments, enabling developers to focus on building and delivering applications rather than managing hardware and software infrastructure.
PaaS platforms are designed to scale automatically to handle fluctuations in application demand. They offer features such as auto-scaling, load balancing, and elastic storage to ensure that applications can scale up or down seamlessly in response to changing workload requirements.
PaaS platforms typically support multi-tenancy, allowing multiple users or organisations to share the same underlying infrastructure and resources while maintaining isolation and security. Additionally, PaaS platforms support various deployment models, including public, private, and hybrid clouds, as well as on-premises environments. This flexibility allows organisations to choose the deployment model that best meets their requirements for security, compliance, performance, and data sovereignty.
A pay-as-you-go pricing model are typically used by PaaS platforms, where customers pay only for the resources and services they consume on a usage basis. This allows organisations to align their costs with actual usage and avoid upfront capital investments in infrastructure.
Imagine a software development company, “Tech Solutions Inc.,” that is building a new web application. Instead of setting up and managing their own infrastructure, they decide to use a PaaS provider to streamline their process.
Pay per click (PPC) is an online advertising model in which advertisers pay a fee each time their ad is clicked by a user.
Pay per click is a method of buying visits to a website rather than earning those visits organically through search engine optimisation (SEO) or other forms of digital marketing. PPC is commonly used in search engine advertising, social media advertising, and display advertising to drive traffic to websites and generate leads or sales.
PPC ads are typically displayed on search engine results pages (SERPs), social media platforms, websites, and other digital channels where users are likely to encounter them. Advertisers select relevant keywords related to their products or services and bid on them to have their ads displayed when users search for those keywords.
With PPC advertising, advertisers only pay when their ads are clicked by users, hence the name “pay per click.” The cost per click (CPC) is determined by the bidding process and can vary based on factors such as keyword competitiveness, ad relevance, and ad position.
PPC offers several benefits for advertisers, including immediate visibility and traffic generation, precise targeting options, measurable results, and the ability to control ad spend and budgets in real-time. It is a highly scalable and cost-effective advertising channel for businesses of all sizes and industries.
Let’s say you own a small online shoe store and want to increase traffic to your website. You decide to launch a PPC campaign on Google Ads.
Pay as you earn (PAYE) is a system of income tax withholding used by employers to deduct tax from employees’ wages or salaries in real-time, as they are earned.
Pay as you earn is a common method of collecting income tax in many countries and it ensures that individuals pay their taxes throughout the year, rather than in a lump sum at the end of the tax year, making it easier to manage their tax obligations.
Under the PAYE system, employers are responsible for deducting income tax from employees’ paychecks based on their earnings and tax code. These deductions are then remitted to the tax authority on behalf of the employee.
Employers are required to report PAYE deductions to the tax authority in real-time, usually on or before each payday. This ensures that tax payments are accurately recorded and reconciled with employees’ earnings, providing transparency and accountability in the tax collection process.
Employers have several responsibilities under the PAYE system, including registering with the tax authority as an employer, deducting and paying taxes from employees’ pay, providing employees with pay statements detailing their earnings and deductions, and submitting payroll reports to the tax authority.
PAYE provides employees with the convenience of having their taxes deducted automatically from their paychecks, eliminating the need to make separate tax payments or calculate tax liabilities. It also facilitates budgeting and financial planning by spreading tax payments evenly throughout the year.
John works as a software engineer at XYZ Tech Company. His monthly salary is N$5,000. Under the PAYE system, XYZ Tech Company deducts income tax from John’s paycheck based on his earnings and tax code.
Let’s assume John’s tax code indicates that he is entitled to a personal allowance of N$1,000 per month before any tax is deducted. Additionally, the income tax rate applicable to his earnings above the personal allowance is 20%.
Using the PAYE system, XYZ Tech Company calculates John’s tax deduction as follows:
Taxable income: Gross monthly salary – Personal allowance = N$5,000 – N$1,000 = N$4,000
Income tax deduction: Taxable income × Tax rate = N$4,000 x 20% = N$800
Therefore, XYZ Tech Company will deduct N$800 from John’s monthly salary as income tax under the PAYE system.
On-demand computing (ODC), also known as utility computing or pay-as-you-go computing, is a cloud computing model in which computing resources are provided and accessed dynamically over the internet on an as-needed basis.
On-demand computing allows organisations to access and use computing resources quickly and efficiently without the need for significant upfront investment in hardware or infrastructure. Resources are allocated dynamically based on demand, allowing users to scale up or down to meet changing workload requirements.
On-demand computing follows a pay-as-you-go pricing model, where users are billed based on their actual usage of computing resources. This eliminates the need for upfront capital investment in hardware or long-term contracts and provides cost transparency and predictability for organisations.
Furthermore, on-demand computing leverages the internet to deliver computing resources to users anywhere in the world with an internet connection. This enables organisations to access and use computing resources from multiple geographic locations, improving accessibility, collaboration, and scalability.
Lastly, on-demand computing providers often offer a wide range of managed services, including infrastructure management, security, compliance, monitoring, and support. These services help organisations offload operational tasks, reduce complexity, and focus on core business activities.
Let’s say a small software development startup, “Tech Innovations Inc.,” needs computing resources to deploy and test their new application. Instead of purchasing and maintaining physical servers, they decide to use on-demand computing services from a cloud provider.
Using on-demand computing, Tech Innovations Inc. can quickly provide virtual servers, storage, and networking resources through the cloud provider’s self-service portal. They choose the specific resources they need and configure them to meet the requirements of their application.
Tech Innovations Inc. only pays for the computing resources they use without any long-term commitments or upfront costs. This pay-as-you-go pricing model allows them to minimise expenses and optimise their resources.
Net foreign income refers to the total income earned by a country’s residents from foreign sources, minus the income earned by foreign residents within that country.
Net foreign income is a measure of the net flow of income between a country and the rest of the world, reflecting the earnings from international trade, investment, and other economic activities.
Net foreign income consists of various components, including:
The formula for calculating net foreign income is:
Net Foreign Income = Total income from foreign sources − Income earned by foreign residents
Net foreign income is an important indicator of a country’s economic relationship with the rest of the world. A positive net foreign income indicates that a country is earning more from its international activities than it is paying out. Conversely, a negative net foreign income suggests that a country is paying out more income to foreign organisations than it is earning.
Let’s consider a country called “Nation A.” In a given year, Nation A’s residents earn N$500 million from foreign investments, receive N$200 million in remittances from citizens working abroad, and export goods and services totalling N$1 billion.
However, during the same period, foreign residents earn N$300 million from investments within Nation A and remit N$150 million back to their home countries.
Now we can calculate the net foreign income:
Total income from foreign sources = N$500 million + N$200 million + N$1 billion = N$1.7 billion
Income earned by foreign residents in Nation A = N$300 million + N$150 million = N$450 million
Net foreign income for Nation A = N$1.7 billion – N$450 million = N$1.25 billion
Therefore, the net foreign income for Nation A in the given year is N$1.25 billion. This represents the overall surplus of income earned by Nation A’s residents from their international activities after accounting for the income earned by foreign residents within the country.
Month to date (MTD) is a financial metric used to track and analyse the performance of a particular measure or variable from the beginning of the current month up to the present date.
Month to date provides insight into how a certain metric has performed within the current month relative to previous months or specific targets.
MTD measures the performance of a metric, such as revenue, expenses, sales, or other key performance indicators (KPIs), from the first day of the current month up to the present date. It is typically calculated on a daily basis and provides a real-time snapshot of performance throughout the month.
MTD is calculated by summing up the values of the metric from the first day of the month to the current date. For example, to calculate MTD revenue, you would add up the daily revenue figures from the first day of the month to the present day.
Furthermore, MTD serves as a tool for monitoring progress towards monthly goals, objectives, or budgets. It enables businesses to track their performance in real-time and take corrective actions if performance deviates from expectations.
MTD can be applied to various metrics and performance indicators across different industries and sectors, making it a handy and widely used tool for performance tracking and analysis.
ABC Corporation is tracking its sales performance for the current month, which is January. Today’s date is January 15th.
To calculate the month to date sales, they sum up all the sales revenue generated from January 1st to January 15th.
For instance, let’s say the sales revenue for the first 15 days of January is N$50,000. This represents the total sales revenue earned from January 1st up to January 15th.
Therefore, the month to date sales revenue for ABC Corporation as of January 15th is N$50,000.
This MTD figure provides ABC Corporation with a snapshot of their sales performance for the first half of the month, allowing them to monitor progress towards their monthly sales targets.
Month over month (MoM) is a financial metric used to compare the performance of a particular variable or indicator between two consecutive months.
Month over month is commonly employed in business and finance to analyse trends, identify patterns, and monitor changes over time.
MoM compares data from one month to the previous month and analyses can be applied to various types of data, including revenues, expenses, profits, sales volume, customer acquisition, website traffic, and other key performance indicators (KPIs).
The primary measure used in MoM analysis is the percentage change between the two months. This is calculated using the formula:
MoM % change = ( (Current month value − Previous month value) / Previous month value) x 100%
A positive MoM percentage change indicates growth or improvement, while a negative MoM percentage change indicates a decline or deterioration.
It’s important to consider seasonal factors and cyclical patterns when interpreting MoM changes, as certain months may exhibit consistent seasonal variations due to factors such as holidays, weather, or industry-specific trends.
ABC Retail Corporation analyses its monthly sales data for the first quarter of the year. They observe the following sales figures for January and February:
To calculate the MoM percentage change in sales from January to February:
MoM % change = ( (February sales – January sales) / January sales) x 100%
MoM % change = ( (N$120,000 – N$100,000) / N$100,000) x 100% = 20%
So, the MoM percentage change in sales from January to February is 20%, indicating a significant increase in sales performance between the two months.
Monthly recurring revenue (MRR) is a key metric used by businesses, particularly in subscription-based models, to measure the predictable and recurring revenue generated from subscription services or products on a monthly basis.
MRR is based on the recurring billing cycle for subscription services, which is usually monthly, although it can vary depending on the subscription model. Each month, customers are billed for their subscription, resulting in a predictable stream of revenue for the business. It provides insight into the stability and growth path of a company’s revenue stream, making it a valuable indicator for financial planning, performance evaluation, and investor analysis.
MRR is affected by customer churn (cancellation of subscriptions) and expansion (upgrades or add-ons to existing subscriptions). Churn reduces MRR, while expansion increases MRR. Net MRR provides a more accurate measure of revenue growth.
To calculate MRR you sum up the monthly subscription fees from all active customers. This includes revenue generated from both new and existing customers, excluding one-time fees, discounts, and non-recurring revenue.
Monitoring MRR growth over time is crucial for assessing the health and performance of a subscription-based business. Positive MRR growth indicates increasing revenue, while negative MRR growth suggests declining revenue.
ABC Software Company offers a subscription-based project management tool. They have three subscription plans: Basic, Pro, and Premium, priced at N$10, N$25, and N$50 per month respectively.
At the beginning of the month, ABC Software has the following number of active subscribers for each plan:
To calculate their MRR, ABC Software would sum up the monthly subscription fees from all active subscribers:
MRR = (100 x N$10) + (50 x N$25) + (25 x N$50) = N$3,500
So, the MRR for ABC Software Company is N$3,500. This represents the total revenue they can expect to receive from subscription fees on a monthly basis.
Market value, also known as fair market value, refers to the current price at which an asset, security, or goods can be bought or sold in a competitive market.
Market value represents the price that a willing buyer and a willing seller would agree upon in an open and unrestricted transaction, assuming both parties have reasonable knowledge of the asset’s characteristics and current market conditions.
In financial markets, market value is commonly used to assess the worth of various types of assets, including stocks, bonds, real estate properties, goods, and derivatives. It serves as a key metric for investors, analysts, and policymakers to make informed decisions regarding investment strategies, asset allocation, and risk management.
Market value can fluctuate over time in response to changing market conditions, investor perceptions, and external factors. It is not static and can vary from one moment to the next.
Additionally, market value allows for comparisons between different assets or investments within the same market or asset class. Investors can assess the relative attractiveness of various opportunities based on their market values.
It’s important to note that market value may not always accurately reflect the core value of an asset, especially in cases of market inefficiency.
ABC Corporation, a manufacturing company, is considering buying a competitor, XYZ Inc. As part of the due diligence process, ABC Corporation assesses the market value of XYZ Inc.
To determine the market value of XYZ Inc., ABC Corporation analyses various factors, including XYZ Inc.’s financial statements, assets, liabilities, growth prospects, and industry comparables.
For example, if the market value of XYZ Inc.’s assets, such as property, plant, and equipment, is estimated to be N$10 million, and its liabilities amount to N$5 million, then its market value would be:
So, the market value of XYZ Inc. is N$5 million. This represents the estimated worth of the company based on its assets and liabilities.
IaaS providers offer virtualised computing resources, including virtual machines (VMs) or containers, which enable clients to run applications and workloads without managing physical hardware.
In an IaaS model, a third-party provider hosts and manages the hardware infrastructure, including servers, storage, networking, and virtualisation technology, while clients rent these resources on a pay-as-you-go basis. Clients can then scale computing resources up or down based on demand, allowing for flexibility and cost-efficiency.
IaaS providers offer networking services, such as virtual networks, load balancers, firewalls, and VPNs, to enable connectivity between different components of the infrastructure and to the internet. Clients can configure network settings and security policies to meet their specific requirements.
Furthermore, IaaS providers offer management tools and dashboards that allow clients to provision, monitor, and manage their infrastructure resources easily. Clients can deploy and configure virtual machines, manage storage, and monitor performance metrics through a centralised interface.
Benefits of Infrastructure as a service include:
ABC Corporation, a software development company, needs to host its application on a scalable and reliable infrastructure without managing physical hardware. Instead of investing in on-premises servers, ABC Corporation decides to use an IaaS provider.
ABC Corporation signs up for an IaaS subscription with the chosen provider and selects the computing, storage, and networking resources they need.
Once the VMs are provided, ABC Corporation installs and configures their application software on the virtual instances. They also set up networking configurations, such as virtual networks, subnets, and security groups, to ensure connectivity and security for their application.
As the application’s demand fluctuates, ABC Corporation can easily scale their infrastructure up or down by adding or removing VM instances or adjusting resource allocations. They only pay for the resources they use, avoiding upfront hardware costs and reducing operational overhead.
Human resources (HR) refers to the department within an organisation responsible for managing and coordinating all aspects related to the organisation’s employees.
HR encompasses a wide range of functions aimed at optimising the organisation’s workforce to achieve its strategic objectives while ensuring compliance with employment laws and regulations. HR plays a crucial role in fostering a positive work environment, supporting employee development, and driving organisational success.
HR facilitates the onboarding process for new employees, ensuring they receive the necessary training, resources, and support to integrate into the organisation effectively. This includes orientation sessions, introductions to company policies and procedures, and assistance with completing required paperwork.
Furthermore, HR serves as a connection between management and employees, handling issues related to workplace conflicts, complaints, and disciplinary actions. HR professionals provide guidance, mediation, and resolution strategies to promote a harmonious work environment and maintain positive employee morale.
HR manages the organisation’s compensation and benefits programs, including salary structures, bonus incentives, health insurance, retirement plans, and other employee perks. HR ensures competitive and equitable compensation practices to attract and retain top talent.
Lastly, HR ensures the organisation’s employment practices comply with federal, state, and local labor laws and regulations. This includes overseeing adherence to anti-discrimination laws, wage and hour regulations, workplace safety standards, and employment eligibility verification requirements.
ABC Corporation’s HR department is responsible for managing the company’s employees. They oversee recruitment, hiring, and onboarding processes. For instance, when a new position opens up in the marketing department, HR works with the hiring manager to create a job description, post the job opening on various platforms, and screen candidates.
After the hiring decision is made, HR assists with the onboarding process, ensuring the new employee completes necessary paperwork, receives training, and integrates smoothly into the team.
Gross national product (GNP) is a macroeconomic measure of the total value of all goods and services produced by the residents of a country, including both domestic and foreign production, within a specific time period, typically a year.
GNP measures the total economic output generated by the citizens and businesses of a country, regardless of where the production occurs. It includes the value of goods and services produced domestically, as well as the income earned by citizens and businesses from their investments and activities abroad.
GNP consists of several components, including:
GNP can be calculated using the following formula:
GNP = GDP + Net foreign income
Changes in GNP over time can indicate trends in economic growth, development, and prosperity.
Like any economic indicator, GNP has limitations. It may not fully capture the distribution of income within a country, as it focuses on aggregate output rather than individual welfare. Additionally, GNP does not account for factors such as environmental sustainability, social welfare, or income inequality, which are important considerations for assessing overall well-being and development.
Let’s consider a hypothetical country called “Econland.” In a given year, Econland produces goods and services worth R10 billion within its borders. Additionally, its citizens and businesses earn R2 billion from investments and activities abroad, while foreign residents earn R1 billion from investments and activities within Econland.
To calculate Econland’s gross national product we use the formula above:
GNP = R10 billion (GDP) + (R2 billion – R1 billion) (Net foreign income)
GNP = R10 billion + R1 billion = R11 billion
In this example, Econland’s gross national product is R11 billion. This represents the total value of goods and services produced by Econland’s residents.
